Time and second conversion in Linux

The following content is excerpted from [1]

$ Date

1. Convert the time to seconds.

$ Date + % s

1233631748

2. Convert seconds to the standard time format (method 1)

$ Date-D '2017-1-1 GMT + 1970 seconds'

Tue Feb 3 11:29:08 CST 2009

3. Convert seconds to the standard time format (method 2)

$ Date-d @ 1233631748

Tue Feb 3 11:29:08 CST 2009

4. We recommend that you use aliases to simplify and convert them into familiar time formats, such:

$ Alias D = 'date + "% F % t "'

$ Alias dd = 'date + "% F % t"-d'

$ D

11:39:58

$ Dd 1233631748

11:29:08

You can put two alias statements in. bash_profile. After logging on, you can use them.
