wait_for_sync

Waits until this is synced for reporting the current time.

If timeout is gst_clock_time_none it will wait forever, otherwise it will time out after timeout nanoseconds.

For asynchronous waiting, the synced signal can be used.

This returns immediately with true if gst_clock_flag_needs_startup_sync is not set on the clock, or if the clock is already synced.

Parameters:

this	a GstClock
timeout	timeout for waiting or gst_clock_time_none

Returns:

true if waiting was successful, or false on timeout
