How to get the time?
Format:%time%

This is the date and time to get the system standard format, but sometimes we need to use the prescribed format, what to do?

Format:%date:~x,y% and%time:~x,y%
Description: X is the start position, Y is the number of characters acquired

For example, I want to get the full date and time,
Format:%date:~0,4%%date:~5,2%%date:~8,2%%time:~0,2%%time:~3,2%%time:~6,2%
Results: 20120731111039
But if the time is earlier than 10 o'clock, then only show the date does not show the time, such as: 20120731, how to solve it?
Format:%date:~0,4%%date:~5,2%%date:~8,2%0%time:~1,1%%time:~3,2%%time:~6,2%
Results: 20120731052539

This will achieve our goal, the success of the date and time.
