Google Apps 脚本：时间驱动触发器时区问题

Question

I'm attempting to build a basic Time Driven Trigger in Google Apps Script to run a function at a specified date and time.

My code is as follows:

function createTimeDrivenTriggers() {
ScriptApp.newTrigger('myFunction')
    .timeBased()
    .atDate(2019, 12, 29)
    .atHour(12)
    .nearMinute(5)
    .create();
Logger.log("Trigger started!");
}

function myFunction() {
  Logger.log("I was triggered!");
}

However, each time I try to run the createTimeDrivenTriggers function I get the following error:

You cannot schedule an event in the past. (line 7, file "Triggers")

At the time of writing 2019-12-29 12:05 was not in the past (in my timezone). This made me think that the script is running in a different timezone than I am.. is that the case? If so, how do I set the script to default to the user's timezone?

This script is part of a Google Sheets Add On, I confirmed that my Google Sheets timezone is set to my local.

How about this answer? Unfortunately, atDate and atHour cannot be used, simultaneously. In your case, atDate is used and the trigger is tried to be installed as 2019-12-29 00:00 . So such error occurs.

When you want to install the time-driven trigger for 2019-12-29 12:05 , how about modifying as follows?

Modified script:

From:

 ScriptApp.newTrigger('myFunction') .timeBased() .atDate(2019, 12, 29) .atHour(12) .nearMinute(5) .create();

To:

 ScriptApp.newTrigger("myFunction") .timeBased() .at(new Date(2019, 11, 29, 12, 5)) .create();

Note:

• In this case, please use 11 for December. Because the initial index of month for Date is 0 .

  monthIndex: Integer value representing the month, beginning with 0 for January to 11 for December. Ref

References:

• atDate(year, month, day)
• atHour(hour)
• at(date)
• Date

If this was not the direction you want, I apologize.
