javascript - Run a Gmail Google Apps Script daily at 8:00, 12:30, 17:00

Question

I need to run a Google Apps script three times a day: at 8:00, 12:30, 17:00.

How to do this?

I have already looked at Triggers, and more specifically Time driven:

• Hour timer, but Every hour, Every 2 hours, Every 4 hours are not adapted here

• Day timer, but then 8am to 9am is not very precise, I would prefer something more precise, and also 12:30 is not possible

• Specific time, but then YYYY-MM-DD HH:MM is not adapted to run it daily

From calendar triggers does not seem adapted either.

Answer 1

Use nearMinute() and atHour():

const createTrigger = ([hour, minute])=>
  ScriptApp.newTrigger("myFunction")
  .timeBased()
  .atHour(hour)
  .nearMinute(minute)  
  .everyDays(1) 
  .create();

[[8,0],[12,30],[17,0]].forEach(createTrigger)
