Thank you both, I'm sure that answers my question.

I've done something like this (pseudo code).
now = currentTime;
target = now + 3500
do something

I'm completely new to D and find the help pages on this
subject very confusing (or at least a bit too detailed for a

how to go about this?
Many thanks

You can get the current 'system time' from std.datetime using
Clock.currTime.
Subtracting one SysTime from another results in a 'Duration',
which you can then compare to your target duration:
var startTime = Clock.currTime;
doSomething();
while(Clock.currTime - startTime < 3500.msecs)
{
executeFunction();
}
Clock.currTime uses a high performance timer,
QueryPerformanceCounter on Windows for example, so you
shouldn't have to worry about timer accuracy.
