Q: Is there a list of the time zones [and daylight saving time/ summer time] changes in Windows?"

A: yes, there is a list of all changes included in KB article 933360, "August 2007 cumulative time zone update for Microsoft Windows operating systems," that notes that the following changes have been made since the previous Windows cumulative time zone update in February (KB article 931836) :

  • Caucasus Standard Time:   Changes display name to Caucasus Standard Time as cities in the previous display name have separate time zones, and removes DST settings. 
  • Armenian Standard Time:   Creates a new time zone for Armenia to better align with different DST changes in the Caucasus region. 
  • New Zealand Standard Time:   Adjusts DST start dates and end dates according to changes signed in to law after the prior cumulative time zone update was created (February 2007).
  • GTB Standard Time:   Corrects the display name for GTB Standard Time on Windows Server 2003 SP2 to include Bucharest. 
  • Jordan Standard Time:   Adjusts DST start times, end times, and dates according to changes signed in to law after the prior cumulative time zone update was created (February 2007). 

A list of the display names and GMT offsets are noted here for your review...
