Hello
I have installed a Cygwin ntpdate ver. 3.2 (beta) on Windows 2000
Server. There I have a problem after change time on our server with daylight
saving mechanism. I'm in GMT+01:00 zone and few days ago our clock was changed
from 02:00am to 03:00am o'clock. From this moment command :
ntpdate -q xx.xx.xx.22
started to return wrong diff (3600sek) between local Windows server time
and our NTP server time. It seems like ntpdate -q try to compare windows +01h
time with basic NTP server time - without +01h (I have a ntp-4.1.2-0 on my Linux
server machine).

-------
I think that "transmit timestamp" should be a "originate timestamp"
value and then the problem would not be exist. Is it can be a problem in
implementation ? Did anybody observe similary problem or can check it in your system ?
Regards
