Whole sky "jumps" while using Date/Time window

[Montclaire Havelin]

The whole sky "jumps" for a large number of degrees if I use Date/Time window dialog and try clicking the arrow to display the next day for the transition from 2012/10/27 to 2012/10/28, or backwards from 28th to 27th (transition is smooth/gradual for other surrounding dates as far as I have seen). If I let the time past during those two days (at any speed) this does not happen and the transition is smooth. The problem is not only that it jump but the fact that everything stays shifted that way which means that the subsequent dates are unreliable if next day arrow is used (which is the right position after that jump than?).

This happens on Stellarium 0.11.4 on 64-bit Fedora 17 Linux, from official distribution repository package.

This is not a bug. It is related to Daylight saving time adjustment.

Many countries have their Daylight saving time change for 2012 on March 25th and October 28th, which means an hour jump.

If you go by hours using the Date/time window and you are about to reach 03:00 AM on 28th October 2012 the time will go back one hour t o 02:00 AM.

You are right, I forgot about daylight saving. Still it's a bit awkward
this way. Maybe a user could be notified about this (and even be given an
option to be notified in the future), or the hour could shift silenty (as
it does now if you just let the time move) instead of the sky shifting an
hour. So just a suggestion for consideration, thanks
