Oh yeah, 33.3mHz. I'm concerned about latency issues
and use them only as a backup. I don't know if they are
just a repeater for the American time sources.

Any sort of time delay won't be an issue with a manual set clock. A
signal from either CHU or WWV will take but a small fraction of a
second. Maybe .02 seconds, or less. If you can set your clocks to the
top of the minute at 59.98 seconds, go for it.

CHU and WWV are independant and quite accurate. Whichever is received
well works well.

Something else I was thinking about the last couple
days that gave me pause: If the noise floor has gone up
so much lately for world band, then how come it is only
these time signals that I can't pull in as readily as I used
to years ago?

Dunno. Seems to be on your end.

If you just want an accurate clock, you might consider a so-called
"atomic clock". They aren't actually atomic clocks, although they are
clocks synced to the NIST atomic clock through WWVB. I have one which
is quite portable, smaller than most SW radios. it sets itself, resets
itself, automatically corrects for DST and has a highly accurate second
counter.

If you have a GPS device, it displays highly accurate time. Cellphone
time should be more than accurate enough for manually adjusted clocks.
