Not exactly an urgent one but something I've just noticed.
I've just sent an email to someone and the time on my system clock had just clicked over to 15:25. However, I go to my Sent Items and the time stamp is 15:26. It wasn't a massive email and it disappeared from the Outbox while my system clock was still on 15:25. I don't think it will change my life significantly if this carries on but I thought someone might know why and how this happens.
