I need to get the date when a particular process was started by PID.

For this purpose, I use:

stat -c %y /proc/PID

In the output, I get the date in the following format:

2021-07-04 11:00:20.352976946 +0300'

But I need it in seconds since the epoch.

Is it possible somehow?

    Do you know about the on-system documentation? man stat for example

You can use %Y instead of %y.

stat -c %Y /proc/28

From man stat:

%Y time of last data modification, seconds since Epoch
