How to work with timezones and full_day scheduler

We’ve set full_day to true on our scheduler. But when we create a new event, it looks like the start/end times are midnight UTC but are then converted to local TZ (so they appear 7pm - 7pm).

What’s the right way to deal with this? I realize we could clear the hours/minutes before the lightbox is displayed.

I also see that server_utc defaults to false. I tried setting that but didn’t help

Or should we just force everything to UTC somehow?


Please update the code in the snippet tool
share with me the updated link and specify steps how to reproduce the issue.

Thanks that helped, I think I found the issue with our code, it was some issue with the year_view, but I was having difficulty reproducing the entire issue with the smaller code sample.

But I was able to demonstrate at least part of the issue here:

Create a new event from the month view and the all day is checked, do it from the year view and it is not.

Add the code below to the onBeforeLightbox handler to solve the issue.

scheduler.attachEvent("onBeforeLightbox", function (id){
	var mode = scheduler.getState().mode;
    if(mode == "year" && scheduler.getState().new_event){
      var ev = scheduler.getEvent(id);
    return true;


Yea, I can always force it (which is what I was doing). Just unclear why I needed to do that (wasn’t clear how the TZ translation (which is what it looked like was going on) was being done).
