I have a PCI-X board with an FPGA which implements a clock running
at 320 MHz. The 320 MHz can
Just redoing a PC in the shop. Don't know if I've suggested a program
called NMEATime to the nuts. I've had this program running on everything
from Win2k to Win7, no hitches. It will sync the PC clock to either a
GPS or to a network signal, at a chooseable update period. Highly
recommended and
Good old nema time. Indeed I started using it on win98 or was it 95?? Way
back is the right answer. In fact I have a very old laptop that essentially
runs just that program. It also generates time codes. IRIG B as I recall
and thats what really made it useful.
Good top know they are still around
I have a copy and I like it, however you can just set your system scheduler
to update your clock more often. Win 7 is 1x a week out of the box but
it's easy enough to set to once every 15 minutes if you want. It's also
free.
Yeah. I just found out that my XP and 7 systems can do this update. Red
face! Just goes to show ya.

If you have a Thunderbolt, Lady Heather will sync your time for free... It
can sync the time via a keyboard command (TS) or via command line options on a
regular basis, or whenever the system clock and GPS clock differ by a given
amount. You can specify the inherent delay between the
Dunno. Does the NMEA driver work on the Meinberg NTP for Windows?
Yes, although from some GPS devices the jitter may be worse than from
Internet servers (depending on your connection). Given that NTP is free,
works extremely well, is well documented, and can be monitored and managed

I hear of folks measuring time delay of off-air radio signals, where
millisecond accuracy is required. Data from multiple receivers in

The obvious one is you can be a real time nut. :)
With a good clock, you can measure network delays.
The normal way that ntp works is to exchange packets
