DTV clock screwed up

Using a set-top DTV converter, analog TV. Works fine, except for about a
week now the clock appears to be an hour slow.

I say "the clock" as if it's part of the converter, but apparently the
box gets the time from the TV stations; I notice the time changes
slightly from channel to channel sometimes. But every channel shows the
clock an hour behind. All other info--program titles, etc.--seems to be
correct.

Any way to fix this? The only options that can be set through the
on-screen menu are:

o Clock: Time zone is selectable (correctly set to Pacific)
Daylight saving option is set to "Auto"

Can't see anything else that can be tweaked here.

So does the STB get the time from the stations? Is there an internal
clock? If so, why can't I set it?

Have you tried 'lying' to it, and setting the time zone to 'Mountain'?

Or setting the daylight saving to 'manual'? See if this has any effect -
or if the converter ignores you.

*Exactly* an hour? (don't judge by your local wall clock;
notice the time when TV programs change and see if it coincides
with the time posted in the EPG)

It is possible the DST algorithm is wonky (Congress changes it
pretty regularly so who knows what the folks who made the converter
box *assumed* to be the rule).

What other options does the DST setting support?

Let me guess, cheap chinese crap right? The problem is that the DST
was implemented incorrectly (which makes me wonder what else they got
wrong if they could not even get DST right!)

Turn the Daylight saving option to 'off' or 'manual'.

What model DTV tuner? I have a Zenith DTT901 (Best Buy sold a rebranded
one under their own name) and it acts like that. It's up to the station
to set the correct time. Many do not. The DTT gets it's time from the
current channel, or the last channel possible if it can't find a time
signal.

It the daylight savings time phenomema. Many computer with older
operating systems suffer from the same Congressional-induced
problems. Another example of our dependence on electronics. If we
ever go to war, we will lose because all our missle control systems
use non-USA made electronics and spare parts will not be available.

Yes, I forgot to mention that mine's also a DTT901. Thanks for
confirming what I thought about the source of the "clock".

I actually really don't care about this problem much, more just
curiosity. Apparently it's a problem with interpreting DST and when it's
implemented (I guess it was recently changed).

It can be way off. I have cable, and have a DTT901 as a backup as my old
TV didn't have a digital tuner. I have it set up in my AV system, so I
an still use it occasionally to play around and sometimes even watch a
few channels that are not available on cable. Also, the occasional
DX'ing (I picked up Cleveland from Chicago once!!)

Anyways, at about 8 something PM, I was playing around with it, and on
one channel, it said it was 2:14PM!! Most of the rest are OK.

The main issue with DST will be Halloween week, as the 30th would have
been the last day of DST under the old rules. It's now Nov 6.
