Is it because the race starter's watch is slightly out or at Betfair's end?

Probably your own computer clock. For my bot it checks the time in the header record compared to my computer clock every 15 races (which is about every 20mins to hour as I include greyhounds in my races).
It then adjusts the times to the difference in my pc and betfair. I have found that over time my computer clock slows down and I lose time. So the gap between betfairs header time and my computer gets higher and higher. It took me a while to find this and code in the solution.
The US races sometimes start early but usually they are way behind to the advertised starting time.
It is very rare for any race to start before the scheduled race time, and I can't even remember missing a race in recent memory due to it starting early.
For example I just restarted my bot and it showed this:
Betfair Header Time is 2013-04-03:21:35:42
Computer Time is 2013-04-03:21:35:39
So as you can see even before I started my bot my pc was 3 seconds slower. It will adjust for that now.
