This would be for sure a really useful extension for sieve. The Horde  
Project (www.horde.org) has the same problem for the sieve web  
interface "Ingo" where it is up until now solved by regexp matching  
headers. But as headers can be forged and unreliable (wrong system  
clock at sending site) a sieve extension for access the local system  
time/timezone and compare against it would be preferable.
