For example, one commit is shown as 10 Nov 20:43 in MacHg GUI client, but MacHg (ie. hg bundled with MacHg) from command-line shows 10 Nov 20:44:27. Another is shown as 10 Nov 06:19 in MacHg GUI but 10 Nov 06:18:43 from command-line. A third example shows them both in agreement with MacHg GUI showing commit at 10 Nov 06:17, while the command-line shows it as 10 Nov 06:17:51.
