Set the System Time and Date
The time and date must be set in the STREAM so that video clips, still photos, and other files will have the time
and date that corresponds to the time recorded. It is recommended that the integrator set the time and date
automatically through the application each initialization. The camera has a small real time clock battery
backup that will last a few hours.
The time and date should be set by using the application programming interface to set the time. HTTP
commands necessary to set the time are:
<ipaddress>/api/system/utc=xxx where xxx = -12 to 12
<ipaddress>/api/system/time=xxxxxxxx where xxxxxxxx is the EPOCH time to set the time and date to.
The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed
since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z).
Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but 'epoch' is often used as a synonym for
'Unix time'. Many Unix systems store epoch dates as a signed 32-bit integer, which might cause problems on
January 19, 2038 (known as the Year 2038 problem or Y2038).
It is best to set the time and date each time the unit is powered up. A backup battery does exist to back up the
time and date. This battery lasts several hours and is rechargeable.
