Getting error time is in future

Hi Experts,

When i am trying to post the production order details and confirmation into SAP from MII i am getting the error TIME IS IN FUTURE.

After my investigation SAP time is in GMT and the MII time is in EDT.At the time of posting it is capturing the time from system, so i set my system time with MII time.

Could any one of you tell how to figure out the issue.

Thanks in advance,

Madhusudan.
