Setting the date with the WMOD2

Hi i have a WMOD2 that i am using for a college project.
I am having trouble changing the date on it. The AT+CCLK command hasnt worked for me.
Just wondering if anybody knows how to do this or where i could find an at command set for this modem


What did you try?
What were you expecting to happen?
What actually happened?
What research/investigation/testing/debugging have you done to attempt to account for the difference? (including verifying your original expectation).
