16.2 AT+CCLK Real Time Clock
Syntax
Parameter Description
Format is "yy/mm/dd,hh:mm:ss", where the characters indicate the two last digits of the year, followed by month,
day, hour, minutes, seconds; for example 6th of May 2004, 22:10:00 hours equals to "04/05/06,22:10:00"
Factory default is "02/01/01,00:00:00"
Notes
• <time> is retained if the device enters the Power Down mode via AT^SMSO.
•
<time> will be reset to its factory default if power is totally disconnected. In this case, the clock starts with
<time>= "02/01/01,00:00:00" upon next power-up.
• Each time TC35i is restarted it takes 2s to re-initialize the RTC and to update the current time. Therefore, it
is recommended to wait 2s before using the commands
AT+CCLK and AT+CALA (for example 2s after
^SYSSTART has been output).
