1. A seismic recording system comprising:
- a) a seismic energy source,b) an autonomous data recorder with a field timer that records field time,c) a standard timer that records standard time,c1) a control timer that records control time,d) a processor that corrects the field time from the field timer (b) by using a regional drift, wherein the regional drift is a correction factor calculated using recorded control time and standard time,e) calculating a regression-based model of the regional drift; and
f) modifying the field time using the calculated regional drift.
