When we schedule a batch process to run using UI, which timezone does it run?
Does it run on the user's timezone or the org's timezone or any other.
I need a particular schedulable batch to run on 1 of every month in australian time zone.
Any link to documentation would be helpful
You could also create you own custom apex batch queue. I did this myself and created the GitHub project SObject Work Queue which had the following design goals:
Maybe you want to check if that could be used in you case or collaborate on GitHub to extend it for your purpose.
Here is an overview sequence diagram that shows how work is defined, enqueued and processed in such a custom Apex Queue:
So I've written logic to calculate timezone offsets as an adaptation of some Apex code I found online.
This was for a similar problem where I was calling out with a date/time to webservice that was expecting GMT and was reconverting the values that SFDC was sending after they arrived assuming they were GMT (while I was still using a standard SFDC component).
It took a while, and you might want to modify it, but it includes European timezones.
This isn't a complete set, but is based on the TZ_database on wikipedia.
Hopefully this gets you going in the right direction as far as setting your dates/times.
To use, input the target timezone you want the offset from GMT for, and than you can add that value back to your time input value in hours to get the correct offset for time based on daylight savings time
public static Integer getTZOffset(String targetTimezone) {
Map<String, Integer[]> tzSIDKeys = getTZSidKeys();
Date[] dstDatesNow = getDSTDates(System.Today().year());
Integer UsersTZOffset = 0;
if (tzSIDKeys.get(targetTimezone) != null) {
if (System.Today() >= dstDatesNow[0] && System.Today() <= dstDatesNow[1]) UsersTZOffset = tzSIDKeys.get(targetTimezone)[1];
else UsersTZOffset = tzSIDKeys.get(targetTimezone)[0];
}
return UsersTZOffset;
}

The apex developer guide shows that scheduled jobs follow users time zone
The easisest way would be to use a user who has locale set to australlian timezone else you will have to do the conversion and offset yourself .
From UI it will use current running users timezone .
