GetSystemTime or GetLocalTime

I'm synchronising times amongst a number of clients via a TCP connection.
(I'm in the UK). The correct time will be read from GetSystemTime or
GetLocalTime. The structure is sent to the remote client via TCP and the
client uses SetSystemTime or SetLocalTime.

Should I be using GetLocalTime & SetLocalTime? My client logs the old and
new time so I assume the using Local would be best?

Definitely system time. Otherwise you'll be dealing with the whole
timezone conversion madness. Even if all the clients are in the same
TZ, I'd still go with system. Either way I suspect you'll find out
rather quickly just how many clients are not configured for the
correct local TZ <g>
