The good news is that
offers Windows patches for the new savings time regime for Windows versions
no longer support by Microsoft..

The bad news is that they are only for the NT line, the Windows 95, 98, ME
do not have patches.  I don't know where the Windows keeps rules,

Unix/Linux has an extensive rule set with a complete history so it can
propoerly display past time stamps.  The many comments include references to
sites like for an unofficial but extensive
description of Indiana and a stale link that should be that describes Arizona's rules.

The Indiana page is a real hoot.  There must be something in the air at
the state capital, see also
which apparently would not have legislated a value of pi as is commonly

Perhaps it's "time" to make sure my wind-up clocks still work.
