Does the app synchronise its time for summer time (DST) changes, in different parts of the world? Couid you please add Tehran, Irans time zone which is GMT+3.5 hrs? In my opinion, if I may, in order to show the minutes for cities with half hour difference from the GMT, uoy need to extend the min arrow ueyond clocck-face centre to the other side, in another colour to make it easier to read the time in 1/2 hr zones, thank you!
