Handle SdBusError exception in setting time

sdbusplus now throws SdBusError exception when a sd bus call fails.
When setting time via systemd timedatectl service, it may fail to set
time due to time settings.
So handle this exception and print the reason.

Tested: Verify this service does not crash but prints the exception in
        journal log, when it fails to set time to systemd.
