BIND 9.3.1 TSIG Error Message

[Albert_Ali at aporter.com]

I am receiving the following error message when the slave tries to update 
its zone file: "request has invalid signature: TSIG tsig-key: tsig verify 
failure (BADTIME)"
According to the BIND Manual, this results when  "a TSIG aware server 
receives a message with a time outside of the allowed range, the response 
will be signed with the TSIG extended error code set to BADTIME, and the 
time values will be adjusted so that the response can be successfully 
verified."
How can I resolve this??
