[comp.databases] Day Light Savings Time Switchover Periods

mcmahan@netcom.UUCP (Dave Mc Mahan) (08/15/90)

I have been asked to determine (if possible) when day light savings periods
will take effect.  I am looking for both the autumn date when it ceases to
exist and the spring date when it goes into effect.  I was under the impression
that it occurs on the first weekend in April (at least in the US), but I don't
know when the autumn restoration occurs.  Does anybody know the formula
used to determine these times?  Am I correct about the spring date?
