I am using a Cinterion Modem to pass data from field sensors through the modem unit and back to a central server. As part of this I need to timestamp the data as it passes trough the modem. Every time the modem (TC65i) is swtched on it reverts to 01-01-2002, and my system time miilis then tick from that date. I currently get the time from a time server, set and use AT+CCLK to time stamp every data transfer, but this seems a bit backwards to me, when all I think I need is system millis and a calendar function.
Is is possible to set a system time, or is there a workaround?
Many thianks in advance for any advice.
