This post is in reference to the DST practice in most countries. This affects even those of us in the equatorial belt because we deal with them.

We don’t have DST but during college I adjust my wristwatch to advance by 45 minutes. It is for those who look at my watch (e.g. in public transport) without asking for permission. Then I try not to giggle when I see their expression change drastically when they doubt if they are still on time with their appointments.

This also works even if they have their own clocks because even if they assume that my clock is 30 minutes in advance then they are now already behind by 15 minutes. Sadly the effectiveness of this prank is lessened now that most people have cellphones and the possibility of the internal digital clock being wrong is very, very small. 🙂
