Suggestion:
import sqlite3 and use the SQLite date/time functions. No database required. It will be faster than shelling out to bash al the time.

#python #sqlite #bash

@knu Story time. One place I worked at had a custom php cms. The function in it for getting the current time made a mysql database call to NOW() to get the current time and called that function constantly. I replaced that with the php built in and performance slightly improved.

Getting epoch time from exactly six months ago from now is a simple one liner in #bash due to date from coreutils. No pipes, etc, necessary.

date -d"6 months ago" '+%s'

But you can also use printf builtin with bash if you need something more verbose or want to assign a datetime variable directly.
