English 12-hour to 24-hourHere is how to convert the 12-hour English format to the 24-hour format:
- If the time was 12:00 AM (midnight), it would be 00:00 when converted to the 24-hour clock.
- If the time was between 1: 00AM and 11: 00AM, the 12-hour system and the 24-hour system were the same. For example, 1: 00AM was 01:00, and 11: 00AM was 11:00.
- If the time was 12:00 PM (noon), it would be 12:00 in the 24-hour clock.
- If the time was between 1:00 PM and 11:00 PM, the conversion to the 24-hour system would require 12 to be added to the original number of hours. For example, 1:00 PM was 13:00, and 11:00 PM was 23:00.
In programming, for example, using the Simple Dateformat class of Java, if the format time is in the 12-hour format, use "hh:mm:ss", and in the 24-hour format, use "HH:mm:ss". You can obtain the 12-hour format time and convert it to the 24-hour format according to the above rules.

Photographic exposureWhat you want to ask might be "photography exposure". In layman's terms, exposure was the amount of light a photo received. Too little light would cause the photo to be under-exposed and dark, while too much light would cause the photo to be over-exposed and white.
The exposure was controlled by the three elements of aperture, shutter, and sensitivity:
1. Shutter: The slower the shutter speed (the longer the shutter time), the greater the amount of light entering, and the brighter the photo. Conversely, the faster the shutter speed, the smaller the amount of light entering, and the darker the photo. For example, a high-speed shutter was suitable for capturing fast-moving objects and could freeze a clear picture, while a low-speed shutter could record the trajectory of motion and was used to capture silky water and star trajectories.
2. Light sensitivity: The higher the sensitivity (the more sensitive the camera is to light), the greater the amount of light entering, and the brighter the photo.
3. Aperture: When the sensitivity is constant, the aperture and shutter are in inverse proportion.
In addition, there were different ways of exposure:
1. Average exposure method:
- The exposure was based on the average light measurement value. The subject was taken as a whole, and the average brightness value of the whole was measured at one time and exposed according to this average value. If the subject has a single tone and the brightness is close to medium gray, or if the subject has a difference in light and dark but the light and dark are evenly matched, a better exposure effect can be obtained. However, when the subject is too bright, too dark, or the light and dark area is too wide and the contrast between light and dark is too large, exposure errors may occur according to the exposure recommended by the light meter.
- The average value exposure was to measure the local brightness values of the bright and dark parts of the subject, then average several values, and then expose according to the average value.
2. Regional exposure method: The reflection rate of the scene, the brightness of the scene, the amount of exposure, and the brightness of the image were integrated into 11 gray-scale regions. Level V was the area corresponding to an intermediate gray (18% reflective) object. It was the benchmark for light measurement and exposure. The real areas that could express texture were the seven regions from Level II to Level VIII.
3. High-profile exposure method: It is suitable for the subject to be a bright object with high reflective rate, or most of the subjects are high-brightness objects, such as white, light-colored porcelain, glass, white cloth and other creations, as well as natural scenery such as clouds and snow. The method was to directly measure the brightness of such high-brightness objects, and then increase the exposure by about 3 levels during the exposure, so that the brightness of the image of the bright object fell in the position of Zone VIII.

Online exposureThere were many kinds of exposure on the Internet. On the one hand, some micro-merchants were exposed for violating the rules in their operations, such as selling fake and inferior goods. For example, the owner of a fruit shop in Zhangjiagang City, Jiangsu Province, was found and punished by the Market Supervision Bureau for selling N95 masks without packaging, implementation standards and product qualification certificates in WeChat circle of friends. On the other hand, some of the business models in the micro-commerce industry were also controversial and exposed. For example, some micro-business teams had agency relationships and prices were not transparent. Some people questioned that some micro-businesses 'so-called "leading others to make money" was actually relying on lower-level agents to achieve their own wealth freedom. For example, Brother Lu and Aunt Lu's skincare brand was accused of not having a physical factory and relying on processing and branding production. There was also the problem of confusion between agency prices and sales prices, which caused controversy. In addition, in the development process, the micro-merchants also faced the supervision of the industrial and commercial tax departments. Some large-scale micro-merchants may be investigated for suspected pyramid schemes and other issues. Some of the founders of the micro-merchants were taken away for investigation due to law enforcement in other places.

2. ** Create a personal website or blog **: Show the work introduction, chapter previews, author introduction, etc. Through search engine optimization (SEO) technology, improve the ranking of the website in search results, increase traffic and exposure. Regularly update the content of the blog to attract readers to visit and encourage them to leave comments.
3. ** Participating in online book fair and literary events **: By participating in online book fair, literary competitions, and works collection activities, you can display your works and communicate with readers. This would help increase the popularity of the work, attract the attention of potential readers, and even have the chance to win awards or collaboration opportunities.
4. ** Cooperation with a publishing agency **: You can cooperate with a publishing house or a self-publishing platform to publish your work as a physical book or an e-book. The publicity channels and resources of the publishing house could allow the works to be more widely exposed, increasing sales and readers, while the self-publishing platform could allow authors to publish their works independently, with more control and profits.
5. ** Use book review and book recommendation platforms **: Submit your work to book review websites, book review blog, or book recommendation platforms for professional book reviewers or readers to review and recommend. Good reviews and recommendations would increase readers 'trust in the work and their willingness to buy it.
6. ** Hold offline activities **: Hold offline reading meetings, signing activities, etc., to communicate face-to-face with readers and share creative experiences and insights.

24-hour clockThe 24-hour system was a time recording system that divided a day from midnight to midnight into 24 hours, from 0 to 23 (24 was the midnight at the end of the day). It originated in ancient Egypt, where the Egyptians divided time into 12 hours during the day and 12 hours at night (or 10 hours between sunrise and sunset, 1 hour each at dawn and dusk, and 12 hours at night). At that time, people realized that the length of an hour changed with the seasons. In the 24-hour format, the time is written in the format of "hours: minutes"(for example, 01:23) or "hours: minutes: seconds"(01:23:45), with zeros in front of numbers less than 10 (although it is not necessary in the hour part, it is widely used in computer applications such as the 8601 standard). In an environment where the precision was higher than seconds, the seconds could be expressed in decimals. A day starts at midnight (12:00 or 24:00), and the last minute of each day starts at 23:59 and ends at 24:00. 24:00 on a certain day is equivalent to 00:00 on the next day, and the digital clock displays from 00:00 to 23:59. The establishment of this epoch system benefited from the process of global integration, and it expanded around the world along with the expansion of capitalists. It provided a reference for global synchronization activities and had an important impact on the global economy, politics, and culture.

Is it a day or an hour?The god of value could be related to the day or the hour. From the point of view of the day, there was a god on duty every 360 days a year to monitor the affairs of ghosts and gods in the human world, just like a god on duty every day. There were also different gods on duty every day of the year, and the good or bad luck of the day was determined by the interaction of the gods on duty. From the point of view of the hour, different hours also had different good or bad luck judgments related to the value of the gods. For example, on February 19, 2021, different hours had different good or bad luck judgments. The good or bad luck between 23:00 and 1:00 was the heavenly prison (bad), and the bad luck between 1:00 and 3:00 was the Xuanwu (bad).
