This Sunday November 1 the US and Canada will revert to standard time.
At 02:00 time will be adjusted to one hour earlier.

Some various recorded time announcements:

You may also get time by going to http://www.timeanddate.com and

"Spring Forward, Fall Back". :-)

Here (Silicon Valley (Calif.)) we used to have a special number one
could dial, POPCORN, that provided the current time of day. I believe
Pac Bell discontinued that service over 10 years ago.

I used to run the free BATS (Bay Area Time Service) that people could
call from their computers (via modem) to sync time using multiple time
standards; the antenna for my WWV (now NIST) receiver went down during
the Loma Prieta Earthquake (Oct. 17, 1989) and, given the then
ubiquity of NTP (Network Time Protocol), I didn't re-erect the
(original) antenna and discontinued BATS.

Such is life.

Is this list up to date? The Philadelphia time and weather numbers
were discontinued a while back (covered here.)

***** Moderator's Note *****

You're right: I just check the Philadelphia number, and it's wired IO. I deleted it.

Isn't it a bit ridiculous to call it "standard time" when it's only
observed for five months out of twelve? I think "winter time" would be
a more appropriate name.

You may also get the time by tuning your HF radio to 2.5, 3.330, 5,
10, or 15 MHz, or by looking at your CDMA phone. If you want accurate
time, EndRun Technologies sells a number of devices which can derive
an accurate UTC timebase from the CDMA network. (My NTP stratum-1 at
the office is driven by an EndRun Praecis Ct, since discontinued,
which works quite nicely despite being in the middle of the fourth
floor of a nine-story building.)

There are numerous public NTP servers which provide ~100 ms accuracy
over the network.

While it's true that WWV and CHU will tell you the correct *Universal*
time, they can't tell you how to adjust your clock: some areas of the
U.S. don't observe DST.

What's worse, I have a Scott "automatic" alarm clock is equipped to
automatically adjust for Daylight Saving Time - but on the old dates,
not the current ones.

My wife was an hour late for work last Sunday.

These all give you GMT time, which you have to convert to local time
using some algorithm.

Unfortunately that algorithm changed a few years ago; my parents have
a couple appliances which automatically reset their time to adjust for
daylight savings, but they do so on the _old_ dates and not the
current ones.

I commend everyone to listen to Grandpa Jones' song on the subject.
"I twisted my old clock around 'till it ain't worth a dime. I just
don't understand this daylight savings time."

No, actually, they give you UTC. GMT is only used in the United
Kingdom (and even there most sources which claim to report GMT are
actually reporting UTC).

Yes I remember when the change was made. I was working at the RI
Secretary of State's office and we had to run around and patch all the
Windows boxes so they'd know the correct dates. Another example of
political bovine effluent costing real money.

One of the two phone systems (Had a Definity Prologix G3iV11 and a
Dimension G3iV6 system) the Prologix had a nice little calendar
feature where you could specify the dates for daylight saving time
occurence. I guess this was because at the time Avaya wanted to market
the switch to the world. I know it supported Italian E1 signalling
too.

The G3iV6 on the other hand had be manually reset. And the Audix
system used a similar calendaring application to set the time change.
