Comment 7 for bug 1372061

Currently in unity8 we rely on indicator-datetime translations for time string formats; but since these are no longer in sync with the one's used in unity8, it's not working.

I'm moving the time formatter into the sdk where the translations will be done.
Everything (messaging & alarm/events) should be passing around "time stamps" rather than "time strings", which can be formatted & translated by the UIs inconsistently.
