Re: listening to time signals using pc?

In Australia there are many who do but no store can be set by them as satellite 
links and so on delay the transmission.
In the US many stations - particularly the CBS News stations - have time 
signals but even those are often at least one second delayed.
As I’ve already mentioned they’re not used now and thus little attention is 
paid to their accuracy so we come back to WWV which is probably the most 
accurate audible time signal on the planet and can be heard world-wide.

The simplest explanation is that a time signal allows you to calibrate 
your time piece manually.


Let's go back in time say to when WWV first went on the air back in the 
late 1920's.


At that time, clocks and other time pieces weren't too reliable and - in 
some cases - needed to be calibrated daily with a Time Signal, WWV being 
one of the earliest around.


So you tuned your radio to WWV and waited for the stroke on the 0 second 
of the minute, "58, 59 0", long note which started the count up to the 
next 0 second of the next minute.


WWV has announcements to indicate the time coming up, "At The Time 9 
Hours 48 Minutes Co-ordinated Universal time", that way the person 
setting the time piece has time to be ready for the 0 second stroke.


Of course modern-day time signals such as WWV/WWVH do far more than that 
these days and there's a whole host of different signal services around.


The future of time signals is shaky given that most clocks now can 
adjust themselves thanks to the Internet or an Atomic Clock time signal 
so no need for a human to be involved in the calibration process.


You can find more details about WWV etc on Google - despite what you 
might hear from those who ought to know better > - and Wikipedia.

Still the best way to set time is to tune into WWV/WWVH on a 
Shortwave receiver on 2.5, 5, 10, 15 or 20MHZ, the higher frequency's 
come in well during the afternoon.


WWV was recently upgraded, there was talk of it going off the air.

WWV has been in operation since 1927, impressive.

You can phone WWV/WWVH and hear them that way though again what you 
hear will be delayed at least by a quarter of a second, more likely 
longer.


These are US phone numbers

WWV 3034997111

WWVH 8083354363

You can patch these two different numbers together to simulate 
exactly what you'd hear if you tuned to one of the abovementioned 
frequency's on a Shortwave Radio.


In Australia the best way to set your time piece manually is to find 
a station with an accurate local time signal, I say accurate because 
some are delayed by at least a second owing to satellite links being 
used, ABC being a case in point so that can't always be relied upon.
