This has probably been covered in the past, but is there a way correct or
control a PC (Windows 7) clock with the HP 58503A GPS receiver? I just
bought one (on the way now) and have a copy of satstats50 on hand. I've been
using Dimension 4 and I'm surprised at the size of correction every couple
minutes to my PC clock. I'd be happy if my PC clock were accurate to
plus/minus 100ms.

Ron,
Have you tried NTP?

You may also be able to use the PPS output from your HP 58503a in
conjunction with a serial NMEA feed to sync your PC to much better than 10
ms, but NTP alone should be good enough for 100 ms if you have a
half-decent Internet connection. The only times we've seen issues have been
when the PC's motherboard clock is broken (drift more than 43 seconds/day in
NTP terms).
Some notes on using PPS with Windows may be gleaned here. Although the
device mentioned is no longer available, the general principles will apply.
