Original commit message from CVS:
2005-11-19  Andy Wingo  <wingo@pobox.com>

* gst/gstclock.h (GstClock): Remove offset property. Add
internal_calibration and external_calibration. Fix padding. Pad
also by GstClockTime so we don't run into problems.

* gst/gstclock.c (gst_clock_set_rate_offset): Remove.
(gst_clock_get_rate_offset): Remove.
(gst_clock_set_time_adjust): Remove. Fixes #321712.
