Scheduler & DST.

Scheduler Javascript
#1

Hello all,

Is there any way to disable DST on Scheduler? I’m trying the online demo and when DST starts (10/15/2011) here in Brazil, demo cannot skip to next week after DST begins.

On last year, we have the same problem reported at this forum (viewtopic.php?f=6&t=15551). This a bug occours when Daylight Saving Time starts.

Thank you.

Luis

I try to debug your code about DST start, but I can’t fix it.

I do the following to debug:

  1. create a new html with only dhtmlxScheduler elements and setting default view to week.
  2. Config parameter: noy changed.
  3. open dhtmlxscheduler_debug.js provided on this thread and change week_start at line 2556 to:

week_start:function(date){
var shift=date.getDay();
if (scheduler.config.start_on_monday){
if (shift===0) shift=6;
else shift–;
}
alert((this.add(date,-1shift,“day”)));
return this.date_part(this.add(date,-1shift,“day”));
},

  1. open a webbrowser e point to my new dhtmlxscheduler page.
  2. click on next week and see dates changing.
  3. when i’m at 10/09 week and click again on next week, I can see that date/time reported by that alert inserted at 3rd step is 23:00hs and not 00:00hs like other weeks.

It is a bug on start DST and I do not known how to work around that.

Can you help me?

Best regards,

Hello,

Can’t reproduce this bug with updated dhtmlxscheduler.js above.

What I did:

  1. Switched to Brasilia timezone (GMT -3).
  2. Added scheduler.config.start_on_monday = false;
  3. Navigated to 9 October 2011 (Sunday) and clicked Next week button with the breakpoint set to "return this.date_part(this.add(date,-1shift,“day”));" line.
    At this point this.add(date,-1    shift,“day”) returns Sun Oct 16 2011 01:00:00 GMT-0200 and that’s correct.

Kind regards,
Ilya
