We have implemented Active Directory Federation Services in conjunction with our institutional portal.  The ADFS is load balanced across 4 front end servers and works very well most of the time.  However, an specific error seems to crop up for multiple users that seems to be related to client/server time variance.  How can we modify the tolerance time for the client/server time differences?

The time variance I'm aware of for ADFS is the variance for Kerberos.  You can adjust it with the Maximum tolerance for computer clock synchronization Group Policy setting.  I didn't think this would normally be between clients and server, but between the ADFS proxy and ADFS server, but your situation might be difference.  (Is there any chance one of the ADFS servers or a proxy is drifting by five minutes from the domain controller?

I have checked all of our ADFS servers and they are all spot on.  I will follow your group policy suggestion.  I just wasn't sure where to look for the controlling parameter.  I will let you know if I find our answer there.
