GUP error

All,

I'm seeing this error on one of my GUP logs ...

11:47:58.525 [1784:2524] CSylog::SetOverwriteLogTimeInterval: Error difftime returned a negative value.
 

Can someone tell me what its referring to?

I'm trying to research the error but just haven't gotted the time to as yet.

Any help would be appreciated.

Thanks.
