That's interesting to hear. I haven't needed to figure out the details of how it is calculated. I'm not sure why it would be calculated differently.

>>Hi Eric,

>>I've understood the revision to be equal to the number of seconds since midnight, January 1, 2000, local time, divided by 2
>>
>>>In the AssemblyInfo.VB, say you give the following attribute for the version:
>>>

Assembly: AssemblyVersion("1.0.*")

>>>
>>>The version is made of 4 parts (Major.Minor.Build.Revision).
>>>
>>>The Build number is given the number of days since January 1st, 2000.
>>>
>>>What is the meaning of the revision number? I saw in a book that it is the number of elapsed seconds in the current days since midnight / 2 but the formula is not working. Any ideas?
