Real Time Clock - MTX -4G-JAVA-IoT Hardware User's Manual

12. Real Time Clock

The GSM module attached to MTX-Java-IoT modems contains a real time clock (RTC) to maintain accurate
timekeeping and to enable you to "time stamp" messages.
This RTC is supplied by a separate voltage regulator which is also active when the MTX-Java-IoT is in
power down mode and the power supply VIN is available. An alarm function is provided that allows the
MTX-Java-IoT to wake up in Airplane mode without logging onto the GSM/UMTS network.
The MTX-Java-IoT modems also accommodate an independent super-cap inside to maintain the date
and time of the RTC when the power supply is disconnected. This super-cap will be charged when power
supply is present again.
