Not updating at midnight...

[BKeyport]

I think you see it backwards.

Look at the reset variable again.

This line calculates the difference between the current time and midnight of the next day. It does this by creating a new Date object for the next day at 00:00:00.000 (midnight) and subtracting the current time from it.

The variable timer is then set using the reset variable, so…

new Date(year, month, nextday, 0, 0, 0, 0).getTime() - date.getTime()

Assuming it’s currently 6:30pm on August 8th, 2024.

2024/8/9 0:0:0.0 - 2024/8/8 18:30:0.0
1723186800 - 1723167000 (Dropping the milliseconds if used)
= 19800

then the timer is set using setInterval() to “reset” or 19800 - which would be the next midnight.

After the first one, it should be calculating so close to midnight, it’s an non-issue.

@BKeyport setInterval creates a repeating timer with ONE elapsed time

6:30pm to midnight the next day is 24+5.5

So every 29.5 hours it will fire.
1st correct for tomorrow night,
it will miss tonight’s midnight

And then be off from them on, shifting 5.5 hours later each time

24 hours of seconds is 86400

If you think of it as morning, then it will fire every 5.5 hours. Still not 24

After the first one, it should be calculating so close to midnight, it’s an non-issuee

This part is incorrect. setInterval only looks at the value ONE time.

Sorry, computer is stupid. It has one time event setTimeout, or interval setInterval. Both use the elapsed time only once, at creation

[BKeyport]

@sdetweil The problem is that it’s not firing at all - it was working as is… Now it’s not firing, first, last, middle, or any other time.

[sdetweil]

@BKeyport make your own routine to be called

this.update2()

Prove it fires

[BKeyport]

@sdetweil It’s people like you that drive people out of coding. This isn’t fun anymore.

Is there anyone other than Sam that could explain why this don’t work anymore?

[sdetweil]

@BKeyport that’s very disappointing to hear.

I thought I was being helpful in giving ways to debug the problem.

I do not KNOW why it appears to be failing. None of the changes to the mm core appear to affect updateDom

How about this? not tested.

start: function () {
  this.dailyTimer = null
  const moment = new Date()
  const midnight = new Date(moment.getFullYear(), moment.getMonth(), moment.getDate() + 1, 0, 0, 0, 0)
  const toMidnight = midnight - moment
  setTimeout(() => {
    this.doSomething()
  }, toMidnight)
},


doSomething: function () {
  clearTimeout(this.dailyTimer)
  this.dailyTimer = null
  // Do your job here.
  this.dailyTimer = setTimeout(() => {
    this.doSomething()
  }, 24 * 60 * 60 * 1000)
}

@MMRIZE right, thats a way without interval timer

I added this to compliments with the cron entries to get the interval synched to the minute

 let minute_sync_delay = 1;
		// loop thru all the configured when events
		for (let m of Object.keys(this.config.compliments)) {
			// if it is a cron entry
			if (this.isCronEntry(m)) {
				// we need to synch our interval cycle to the minute
				minute_sync_delay = (60 - (moment().second())) * 1000;
				break;
			}
		}
		// Schedule update timer. sync to the minute start (if needed), so minute based events happen on the minute start
		setTimeout(() => {
			setInterval(() => {
				this.updateDom(this.config.fadeSpeed);
			}, this.config.updateInterval);
		},
		minute_sync_delay);

@MMRIZE one thing

You can’t clear the timer if it has triggered, as the timer has expired. The handle is no longer valid

@MMRIZE @sdetweil

the reporter posted this to my github:

I am not a javascript expert, but have some experience in C++ and
microcontroller programming.
I have had some problems with other MagicMirror calendar modules not
updating the day properly and they also seem to implement workarounds and
have issues with the DOM updating.
I did a little looking into this and it seems there must be some generic
issue with the MagicMirror software allowing modules to implement timers
and date/time functions in realtime.

And Sam - I was telling you that it previously was working and works outside of the MM ecosystem - or at least sets it up to work. that’s what got me pissed off - I had done a slew of debugging and it got down to “have you turned off and on again”

There’s lots of issues I’ve been having - most of them being internal MM functions, that I tend to work around by native JS code and using remote access via the Web server.

For example: Logging. Don’t seem to work for me. Gotta log via console, so I pull up the web server and Edge’s dev tools.
