I'm not familiar with Solaris.  I've never worked with a 58503A, but I have 
worked with the Z3801A and KS-24361.

I'd try ntpd.  There is probably a version that comes with Solaris.

USB probably doesn't support PPS.  I'd expect time to be within ballpark of 
10s of ms, roughly what you would expect with a good network connection so 
use that as a sanity check.

You will need to setup your ntp.conf to use the HP driver, 26.

You will need to setup your 58503A to use UTC in T2 mode.
  :diag:gps:utc 1  (and reboot?)
  :ptime:tcode:format F2

You can check the GPS/UTC setting on the status page, and check the T2 
setting by sending:
  :PTIME:TCODE?
