Time and SIM900

How can I set the time?
I watch the SIM900_AT_Command_Manual_V1.03.pdf ,
and I find the write command is AT+CCLK=
and the format is yy/MM/dd,hh:mm:ss± zz
but I use this command AT+CCLK =<12/12/26,15:04:50+08>, it always returned ERROR

can anybody help me ?

I’ve never tried it on mine but i’m pretty sure you’re not supposed to include the < & >.

Try AT+CCLK =“12/12/26,15:04:50+08”

It's really worked.
