New to ST - Does DST work? (Fall 2020)

[moco80132]

Former Wink user here that replaced it with the ST Hub. Now that we’ve rolled clocks back, all of my lighting that was set to come on at 5pm via the Smart Lighting app, came on at 4pm.

I was unable to find any setting in the app that allows you to tell the Hub to actually be smart about the local time zone or in the automations that I set up.

Doesn’t seem like a stretch that a “smart” hub would know how to set the time via a time server. Or, is it me that is not smart?

It occurs to some users. It should sync up by tomorrow after automations run today and set up the schedule for the next run.

@jdroberts will provide better details

I’ve been here since 2014 and it’s been wrong for some significant number of users every year, twice a year, since that time. They usually get it sorted out in a couple of days, but it’s definitely annoying.

Daylight Saving Time Change Issues (3-8-2020)?

Long time ST user, but first time I had issues with DST. Automations didn’t fire off as expected and it’s very difficult to know if an Automation actually did try to run because there’s no place in any event log to see events from these yet. I spoke to Alexa to kick off a Scene, and at least the Alexa command was logged, but nothing related to the Scene. We really need more abilities to see events initiated from Automations and Scenes. DST issues seem to be an annual event, so just curious if anyone else had issues this morning.

Daylight savings time glitch Fall 2019

So, when does the system change in the fall after DST? Because this morning (when that was supposed to happen) my wake up lights went off based on the old time and woke everyone up an hour early. Why the hell can’t this be fixed? I’ve noticed people complaining about this for years. And then, how do I know when it will be updated or will I have to shift all of my routines 1 hour to accommodate?

Daylight saving time, Spring 2019

Here we go boys and girls. Lay your bets… Whats the chances automations work on time this year? Anyone want to see what the Vegas odds officially are this year? I vote, nope again we are an hour off for at least a day if not 2.

Daylight Savings Time (Spring 2018)

At 2am, well 3am, ST stopped working. Had to hard reboot the hub to get it working again. Could be coincidence, but time is very suspicious. Anyone else? Don’t ask me what I think about Daylight Savings TIme. I want my post to remain free of curse words.

Daylight saving time (Spring 2016)

No big deal I know but what kind of daylight saving time is this? A 3:00 am routine ran at 1:00 am? [image]

ST Blows DST Again... Again... Again

Continuing the discussion from ST Blows DST Again!: @bravenel’s post above was in March 2015 (which, in turn, referred to past failure(s) of DST), and here were are a year later, March 2016, and basic DST / Sunset functional still fail? Yes … that’s a question mark, because I really can’t believe DST isn’t being handled properly. I’m in San Francisco, CA. Timezone: PDT (UTC-07:00). I’m using the SmartThings developed and officially supported standard SmartApp “Smart Lighting”, because I am considering migrating to Hub V2 and want my lighting automations to run 100% locally to minimize latency and risk. I just edited and re-saved a super simple schedule that turns on 3 lights, -15 minutes (before) Sunset. Sunset will be at 19:18h; therefore the lights should turn on at 19:03h…

I won’t post them all, but you get the idea.

[moco80132]

Yes, I do get the idea and by looking at your posts, it would appear Samsung has not given a hoot about DST going on 4+ years. Waiting for things to sync up in a day or two is absurd when the Hub should be getting its time from a master time server based on settings we do not have access to.

@moco80132

DST going on 4+ years

More like 6, but yeah.

You can report it to support if you want, but it just seems to be an artifact of their cloud system.

SmartThings Support

I’m not saying that’s acceptable, there are obviously lots of other cloud-based systems that get this right, but since I’m just another customer, I don’t have any idea of how to get them to fix it.

[moco80132]

So my support ticket was answered with a weak set of instructions to remedy the issue.

I (we) are supposed to go into manage our location, select our geolocation, and zoom out and pick some random spot on the map that is not in our time zone.

Then, we are supposed to go back in and select the correct geolocation and all will be right in the world.

As an IT person for the last 30 years, I find that solution to be weak. The developers should be pointing their Hubs to a stratum 1 time server, or multiple time servers. This can be coded easily enough based on a single setting in the app that allows the user to pick their time zone vs. geolocation.

Once the time zone is selected, the Hub should auto update the time based on the known dates when DST starts and ends - it’s a constant. Unless of course Congress changes it again.

[orangebucket (Graham)]

Is this really as trivial as many seem to believe? Genuine question.

Automations have to schedule their next executions. If they specify them as e.g. x seconds from now a DST change will throw them out by an hour either way. If they specify them as dates and times they are locked to one timezone so again they will be an hour out. If local time of day, well does that make any sense on a cloud system?
