Indeed. The main use of dates in HTTP/1 is communication about objects 
stored on the server and the client has no visible use for information 
about server timezone.

The main use-cases I hear presented for transferring TZ information are 
content personalization or user tracking by the server. In both cases it 
ought to be an optional header which can be a) suppressed by users not 
wanting to distribute such information about themselves and b) used by 
the serve in Vary: lists to signal the content customization.
