Auto-adjusting data log record timestamps

Abstract:

The present disclosure provides a method for automatically adjusting data log record timestamps in response to a change in a system clock. The method includes monitoring the system clock to track changes to the system clock, creating or updating a time delta log when a system clock change is detected, creating or updating a look-up table containing an absolute time adjustment value (ATA) for each time delta record in the time delta log, and adding a time delta ID to the data log record so that when a data log record is retrieved from memory the timestamp forming part of the data log record is automatically adjusted.
