EEM policy is useful when 4G/LTE connected routers sit on a network without NTP reachability. The EEM policy will get UTC time from GPS and install the time on the router with the "clock set" command. When the script is registered it will set the time once every 24 hrs. Must have a GPS antenna connected to the router.
Additional CLI needed on the router:
controller Cellular <number>
lte gps mode standalone
lte gps nmea ip
