UNIX Epoch Time

It is an interesting thing to be able to convert an UNIX Epoch time string into a date using the date(1) utility.

On a macOS machine, you can do the following:

$ date -ur 1700000000
Tue Nov 14 22:13:20 UTC 2023

On a Linux machine, you can do the following:

$ date -ud @1700000000
Tue Nov 14 22:13:20 UTC 2023

You can find the current UNIX Epoch time string on both macOS and Linux as follows:

$ date +%s
1699701896
