Compensating for DST, twice
This Sunday (well, the night between Saturday and Sunday) Israel went off DST[1], meaning that the clocks had to be set to one hour earlier.
Normally I’m a very small believer in letting computers do things automatically, following the old adage that if you want something done right you have to do it yourself (rather than let a computer guess its way at it). And so usually I always set my computer not to compensate for DST automatically, and change the hour myself on the correct dates.
This year I made a mistake. I figured that changing the clock should be trivial enough for Windows XP to manage doing by itself. So I set the computer on Saturday to correct for DST automatically.
And on Sunday morning everything seemed fine. The time on the computer’s clock did indeed move an hour back, and it showed the correct time.
I went to work. I came back late at night.
And found that sometime during the day the computer… moved the time back yet another hour.
From now on I’ll get back to doing complex tasks like this by myself.
---- In Hebrew the DST time is referred to as “Summer Time”/”Summer Clock”, and in contrast the non-DST time is referred to as “Winter Time”/”Winter Clock”[back]

I think we should change the clock is small enough to Windows XP by itself. So I will use the computer on Saturday.

A quirkier complication is that time-based locks on some campus doors may not unlock on schedule Monday morning. That’s because these T3 programmable locks, which are set to open and lock daily at specific times, are hard-coded to the old Daylight Saving Time schedule and cannot be reprogrammed.

The packages generally depend on the distance and the type of service one requests. It is usually suggested to let the moving company handle all the aspects of the moving process as they are attired with professional skills.
