> One very useful feature for this I didn't see listed for lnav was to support adjusting for timestamps in different timezones, like maybe you have a desktop's log in local time that you're trying to reconcile with servers. (A related but less-important bonus would be to be able to specify smaller arbitrary clock drift/offsets for each log.)

You can adjust the timestamps for a file using the ":adjust-log-time" command (https://docs.lnav.org/en/latest/commands.html#adjust-log-tim...). For example, if you wanted to shift the timestamps back an hour, you can do:

    :adjust-log-time -1h

The shift is applied to the messages in the file that the top line in the view belongs to.

If you want to do the shift programmatically, you can UPDATE the "time_offset" column of the "lnav_file" table directly (see https://docs.lnav.org/en/latest/sqltab.html#lnav-file)

Thanks!
