2.) Further information about file time representation!
Showing or hiding files based on their creation date or modification date before 1980 in Windows File Explorer is not a standard feature. Windows File Explorer typically does not provide a built-in way to expand files based on a specific year.Also note that the exact spelling and representation of date formats depends on the version of Windows you are using on your computer. So you may need to adjust the date format to ensure this works correctly.
Representing timestamps in filenames is a common concept where time information is embedded in the filename to indicate when the file was created, modified, or last accessed. Here are some common practices :
Time format : Typically timestamps are represented in the year-month-day-hour-minute-second format. Example: “20231022093000” for the date and time October 22, 2023, 09:30:00.
Separator : Hyphens or underscores are often used to separate the individual elements of the timestamp. For example: “2023-10-22_09-30-00”.
File Type : In some cases, the timestamp is added to the beginning or end of the file name to identify the file type. For example: “Report_2023-10-22.doc” or “20231022093000_Image.png”.
Usage : The use of timestamps in the file name can vary depending on the use case. They are commonly used in data backup, logging, and file organization to ensure you can track the history of files over time.
Time zones : When using timestamps in file names, be sure to make it clear which time zone is being used. This is important when sharing or editing files from different locations.
Automation : In many cases, the generation of timestamped filenames is done automatically by computer programs or scripts to avoid human error.
It is important to establish consistent conventions for using timestamps in file names, especially when multiple people or systems access these files. This helps better organize files and make information easier to access.
Unix timestamp :
The Unix timestamp is the most commonly used method of representing file times. It is a 32-bit integer value that represents the number of seconds since 1970, 00:00:00 UTC.
ISO 8601 :
ISO 8601 is an international standard for representing date and time. It is often used to represent file times.
Example : 2023-10-22T19:15:07-08:00
There are many other formats for displaying file times. Some commonly used formats are :
DD.MM.YYYY HH:MM:SS
YYYY-MM-DD HH:MM:SS
DD.MM.YYYY
YYYY-MM-DD
HH:MM:SS
File systems store file times in various formats. In Windows file systems, file times are stored in a 64-bit integer value that represents the number of 100-nanosecond intervals since January 1, 1601, 00:00:00 UTC. In Unix file systems, file times are stored in a 32-bit integer value that represents the number of seconds since January 1, 1970, 00:00:00 UTC.
File time conversion :
If you want to convert file times between different formats, you can do this via a function in your programming language.
If you want to compare file times from different time zones, you need to take the time zones into account. You can do this using a function in your programming language.
