Here is a good explanation of the situation.
ttp://gpsinformation.net/main/gpstime.htm
asically there should be no problem as the receiver should read the UTC=20
ffset information and correct. Especially a receiver that has been=20
unning all along.
Hi Jim,=20
    It is fine if you get your UTC directly off the satellites, but=20
some of us use on-line time servers and there may be a transmission=20
delay over the www. AboutTime gives good results, but resetting your=20
computer over the www using the link built into Windows can give=20
errors of over 2 seconds, from my personal experiences, depending on=20
the exact time of day. I compare the NIST web signal with the direct =20
MSF Rugby 60 kHz radio signal, which has an accuracy of 20 milli sec. =20
