atomic time w/BS2

Hello, has anyone any info on connecting an atomic time receiver, thru a BS2 or other micro, to·update time on a PC. Is it even possible? I have "atomic time sync" from analogx.com and use it to update·the clock on my pc when connected to the internet. It is possible to set an address in·atomic time sync, to get time info. So, I thought maybe·it would be possible to somehow specify·some kind·address to a serial port connected to the stamp.···· ??·

Jeff,
Are you just trying to update your PC clock with time from something
like a GPS receiver? That can be done easily with VB, no Stamp is
required.
NanoSync makes a nice little GPS reference, around $1500. I'm not
sure if you can pull the info straight out of a Magellan or Garmin
type personal GPS, since they do send info to PCs for mapping
programs, I would expect the time is buried in that string as well.
I don't understand where the Stamp comes in to the equation.
Tim
have an external antenna go on sale or go
'fishing' on the internet for one. You'll find these around for $20-$30 on
sale. Lop off there external antenna and
use the clock part as a doorstop; the receiver circuit is in the antenna. Poke
around the archives searching on
'atomic clock'; there was BS2 code floating around here that can monitor the
output of the clock antenna and create a
string with the current time from the short-wave broadcast. There is info at
the WWV? time transmitter web site that
discusses the pulses. Its been a while but I think that once a minute the ascii
time is encoded at the 'beep' and then
the pulses over the next minute accurately mark the time internals that you
count and use if better than 1 minute
accuracy is necessary. On my someday list is a project to make a 'time server'
for my network out of one of these
antennas. I just remembered that Parallax also used to have the same antenna
and code in a kit for ~$80.. duh!
Finding one of the older atomic clocks on sale would be cheaper scrounge way to
go... Good Luck...
