[Kstars-devel] [bug] KStars should use system time zone and DST data

[Aleksey Khudyakov]

Hello everyone!

I've just submitted a bug about time handling in KStars. Does anyone 
have comments? Bug description is pasted inlne




Now KStars uses its own system for handling time zones and daylsight 
saving time (DST) rules. This is wrong for several reasons:

1. It's not correct. Time zones and DST change over time. KStars cannot 
handle it.

2. They'll become out of date when rules change. In fact they are out of 
date already.

3. It's very complex. We canot make it better than it's already done. 
It's just a wasted effort.

In my opinion KStars should store time internally as julian date or 
something similar. It's simple since it doesn't have to deal with abrupt 
jumps in time when DST kicks in. It's just a number so it's easy to 
manipulate time intervals. Transformation to/from YYYY:MM:DD HH:MM:SS is 
required only  when  time is presented/being read  from user and could 
be done on demand.

On downside it require overhaul of all time handling in kstars.
