Setting Time From Gps On The Camera - Canon EOS 5D MARK IV Instruction Manual

Setting Time from GPS on the Camera

The time information obtained from GPS signals can be set on the
camera. The margin of error is approx. ±1 sec.
If signals from at least five GPS satellites cannot be acquired, the time
cannot be auto updated. [Set now] will be grayed out and not selectable.
Even if [Set now] can be selected, updating the time may not be
possible due to an unfavorable timing of the GPS signal acquisition.
When [Auto time setting] is set to [Auto update], the date or time
cannot be manually set with [52: Date/Time/Zone].
If you use Wireless File Transmitter WFT-E7 (Ver. 2/sold separately) and
do not want to change the time after implementing [Sync time between
cameras], set [Auto time setting] to [Disable] in step 2.
Check the [GPS] setting.
