Mark,
In case you missed my point. I am suggesting you only send time in universal
time between servers. I would convert local time to universal time on the
originating systems only (not pass thru systems).
No matter what server you are on, or how many you pass thru, the time will
still be universal time. Hence there is no worry as to what the local time
is!
To answer your question, DateTime does not itself keep track as to whether
it is in Local or Universal time you need to do this yourself. I normally do
this via the context of the variable.
You can use System.TimeZone.CurrentTimeZone to find out what the current
time zone on your system is.
Hope this helps
Jay
