The AT Commands described in this chapter are related to the TC63's hardware interface. More information

regarding this interface is available with the "TC63 Hardware Interface Description"[2].

19.1 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 July 2005, 22:10:00 hours equals to "05/07/06,22:10:00"

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 TC63 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).
