Displaying a time is more complex than it appears at first glance:
it should respect the user's choice regarding 12- our 24-hour format (but
only when supported by the locale) and follow the LC_TIME rather than the
LC_MESSAGES setting.
So rather than getting it more or less right in various places, it makes
sense to defer to a helper method which hopefully does the right thing. The
method added by this patch is based on _formatTimestamp in telepathyClient
with some minor tweaks:
- there's an additional params parameter which allows enforcing
a time-only format, even on dates other than the current one
- only a single desktop settings object is created and shared between
invocations
