Hide timestamp from journalctl output

Sometimes output have a long line and I need to hide some info.

Before:

$ sudo journalctl --no-pager -u coredns --since='10 min ago'
-- Logs begin at Sun 2023-07-23 09:48:00 +07, end at Sun 2023-07-23 10:10:31 +07. --

After:

$ sudo journalctl --no-pager -u coredns --since='10 min ago'| sed 's/.*\]: //'
-- Logs begin at Sun 2023-07-23 09:48:00 +07, end at Sun 2023-07-23 10:10:33 +07. --

Now you know what to do.
