calendar.js: how to specify the date AND time?

[srustamo]

In file: https://github.com/mementodatabase/scripts/blob/master/android/calendar.js
@param {Arguments} options for date AND time are not clear.

I have three field in my database:
DT - date
TM - time
EN - end time

I want to run a trigger to add an event into Android calendar with date as "DT", beginning time as "TM" and end time as "EN".

So far I'm able to either set a date with
AndroidCalendar.create( entry().field("Title") , {begin:new Date(), allDay:true});
Or time with
AndroidCalendar.create( entry().field("Title") , {begin:entry().field("TM"), allDay:false});
When setting the time, the date field in Android calendar defaults to 1970.

How do I set both date and time referencing "DT" and "TM" fields?
