Error running trigger at specific time using GAS

Question

I get the error message (below) when I run the code. My intention is to create a trigger at exact time 2017-04-03 20:10

ScriptApp.newTrigger('myfunction').timeBased().atDate(2017,04,03).atHour(20).nearMinute(10).create();

Log

Answer 1

You can create a new date object with a specific date and time then use new trigger().At(date), not to be confused with atDate(), function to create trigger at that date and time.

var dt = new Date(2017,03,03,20,10)
//Month index starts from 0 i.e. Jan =0,Feb=1... So on
 ScriptApp.newTrigger('myFunction').timeBased().at(dt).create()

Hope that helps!
