Hi Craig,
thank you for replying so quickly.
To be honest, I can't remember which type I put in when I made the field, but I've tried adding another one in our staging site and from the looks of it - the one I am using on our live LMS is Date (no timezone). I suppose that is what is causing the LMS not to work perfectly :) Also, is there a way to check which type of custom fields we have in some overview?
On the plus side, all users have a correct timezone assigned in their profile.
Yesterday, I've added the criterion to add every user to the previously mentioned audience who is starting on the next day (in the upcoming 1 days) and LMS completed this action today at 12:01 GMT (I see that by the due date & time for a program). This is a good containment measure, but I will introduce another date & time field with time included and test how it goes.
Thank you, Craig, I know where to go from here :) Will let the community know how it went. Oh, and yes, we are using Totara 2.9 at the moment.
Best,
Vlad
