One technical point worth considering is that a goodly proportion of the clocks in Jerusalem do not show the time that the tz database would claim they do. Given rough current estimates that the Arab population of (East) Jerusalem is upwards of 35%, and the likelihood that many of their clocks follow the Palestinian rules for DST rather than the Israeli rules, it seems awkward and inaccurate to use the name of the city for one set of rules but not the other.

Thanks for the link. It's difficult to pick a source from that part of the world without bias. It's an unusual case. It's easier to leave it as it is until someone figures out how people at that location keep track of time. Regards, -sm
