yes, that does make more sense to me. I had thought this but the solaris
man page for zic states:

     SAVE  Gives the amount of time to be added to local standard
     time  when  the  rule is in effect. This field has the
     same format as the AT field (without the w and s suffixes).

That's why I was expecting a 1 and a -1.



ps anyone know where I can get the linux timezone source
files from?  Is there one approved source?
