Time sync to Windows. How?

[marc <gmane@auxbuss.com>]

Hi,

I've managed to get Linux through the door at a client's site <whoop, 
applause> However, it is necessary to time sync desktop client's to a 
Windows server. (This is a strict requirement for reasons that I won't 
go into. Yes, I know how trivial it would be with a Linux server, etc.)

Windows has a "service" called Windows Time, but I haven't managed to 
sync to it from the Linux boxes. Is it possible?

In an attempt to approach this in a sane manner, I installed NetTIme on 
a Windows box for testing. This worked, up to a point - the Linux boxes 
could sync to it - but it has a huge flaw in that it refuses to act as a 
time server when it can't access the sources it syncs from - who designs 
this stuff? Since the server s not always connected to the net, this 
means that the clients lose sync, which is not acceptable in this case.

Basically, all I need is a time service on Windows that will sync when 
sources are available, but continue to allow clients to sync to it when 
they are not.

Any ideas or suggestions?
