getRealTime
Queries the system wall-clock time.
This call is functionally equivalent to func@GLib.get_current_time except that the return value is often more convenient than dealing with a #GTimeVal.
You should only use this call if you are actually interested in the real wall-clock time. func@GLib.get_monotonic_time is probably more useful for measuring intervals.
Return
the number of microseconds since January 1, 1970 UTC.
