Hi all, I work with SAC files for located events with OMARKER set to 0, and so the KZDATE and KZTIME are the origin time parameters, which I extract and use for data processing. Some of my SAC files have slightly different origin times (located using different numbers of stations), and I want to fix this so it's consistent across all the sac files for a particular event. And so that OMARKER is 0 and KZDATE and KZTIME reflects the absolute origin time. Any ideas on how to do this?
