The CDR log time stamp is stored in UTC time and not local time like the Event log, but converted to local time
when displayed in the CDR log.
Changing the time and NTP’s UTC Offset (on the > page) will affect the CDR log time in the
following ways:
Changing the time, either changing the system time or via an NTP update will cause new CDR logs to show
the new time but no change will be made to existing logged CDR events
With NTP enabled, setting a UTC offset will change the displayed time for all the CDR events; the stored
time will remain the same because it is stored in UTC and the offset is applied for display purposes
Enabling or disabling NTP when an offset is configured will cause the display time to change for all existing
events and the UTC time will change for logging future CDR events. This is because, when NTP is disabled,
the current time is treated as UTC with an offset of 0
