Read CDMA Network Time +WNETTIMEGET
Description: This command returns the time as defined in the CDMA network. For time to be returned, the
modem must have CDMA service. Time will be returned in seconds from 1/6/80.
If CDMA service is not present, GMTTime format returns 16 zeros and Julian time returns
ERROR.
The use of CDMA time when handling E911 location data is strongly discouraged since the
CDMA time does not reflect the time the GPS data was retrieved. Furthermore, GPS time and
CDMA time are not exactly the same time constants.
According to IS95A, section 7.7.1.3, local time is calculated by GMTtime – LeapSec + TimeZone.
Note: Daylight savings time is available, but it is already factored into TimeZone and,
therefore, should not be used in the calculation.
The format of the command response output is defined by the AT+WNETTIMEFMT command
setting.
