- Show dates relative to the current time, e.g. "2 hours ago".

Only takes effect for dates shown in human-readable format, such
as when using "--pretty".

+`--date=relative` shows dates relative to the current time,
+e.g. "2 hours ago".
++
+`--date=local` shows timestamps in user's local timezone.
