Daylight Savings Time

Featured Replies

Hi. I am running into issues with Daylight Savings Time. British Columbia, Canada (and several other provinces) have moved to permanent Daylight Savings Time. Overnight eisy automatically turned off DST when it should not have. There doesn't seem to be an option in the Configuration screen to select Canada, Vancouver with no DST and the Daylight Savings check box on the Clock screen is greyed out so cannot change the auto DST option and in the location selection window the Daylight Savings Rule cannot be changed either.

I have tried manually setting a custom time and location but there is a problem with the Timezone Offset (GMT) field such that, whenever I change it manually, the system sets it to GMT -25200, making it impossible.

I have tried hard reboot but doesn't help. I am on version 6.0.4

Any ideas?

Thank you

ErikN

Same issue here. Can't turn off DST, can't customize offset (shows as GMT -25200?!). Also tried selecting Arizona time zone (DST off and GMT-7), but could not customize the latitude and longitude to match my actual location in Vancouver, BC. he configuration again sets the offset to GMT -25.200. Hopefully a solution is available soon as I have numerous customer systems (as well as my own system) that have programs using time of day triggers.

Same issue, Calgary Alberta, temporary fix was to set to Regina Sask.

On the staging repo eisy.ui (1.4.8), when I go to System/Configuration and click on the i at the upper right corner of the sunrise/sunset display graphic, under "Details" there is a box labelled "DST Rule" with a drop down menu that has "off" as one of the options. I haven't tested this.

This will set the time to appear correctly, but if your latitude and east-west location in the corresponding time zone are not close to your current time zone placement your sunrise and sunset times will be inaccurate.

Not sure where in the eisy.ui you are looking at. I have not used the new UI much yet and do not follow your navigation through the interface.

The new UI doesn't help (aside from not saving changes), nor the AC. And yes, the east west location will mess things up.

The only fix for now is Sask TZ.

In the AC under Configuration/System/Clock, I see a check box for "Daylight Saving US-Canada]. If you uncheck this does it solve your problem?

It would leave you at standard time. So time would stay constant, but sunrise and sunset times would be off by about an hour.

Thanks, the location field is locked to a DLS rule for Calgary so nothing can be changed. Which made sense yesterday, not today.

An unlock rule to allow changes would be good. Not sure there is a setting for that.

well..it sounds like the issue that happend every time the time changes, happening to me for years, it will self correct (assuming same issue I have seen) tomorrow

What we need is:

  • Capability to actually enter a value into the GMT offset field that accepts the valid input rather than setting the GMT offset value to -25,200

  • Capability to enable or disable the DST rule

For example, Vancouver, BC, Canada is now on permanent DST at GMT -7

The only workaround right now is to set location to Calgary, AB, Canada to get the correct time, and then add a +1 hour offset to any timers that use Sunrise or Sunset, which is a real pain ☹️

Erik

this is so ridiculous! every time DST changes this is an issue, duh, even my most stupid smart swith can handle this!!

A fix was pushed out this evening (thank you UD for quick response!) so it's working properly for me now w.r.t. correct current time and correct sunrise/sunset times based on section of Vancouver, BC, Canada.

Hopefully others are finding similar success?

Fingers crossed this won't happen again in the spring when many go on DST while some of are / will already be.

No solution here, still showing -8 GMT and yes to daylight savings when selecting Vancouver, BC. Is there an EISY update that I missed?

The fix ErikN mentioned was pushed as a separate update rather than a full ISY/eisy firmware release, so it may not show up the way you'd expect. Worth checking the release notes or changelog for the timezone/DST correction and confirming your unit actually pulled it. If Vancouver still reads -8 GMT with DST enabled after that, the update likely didn't apply on your device. I'd verify the version first before assuming something was missed.

There is a bug in the Admin Console for offset, please use eisy-ui on the latest firmware. Let us know if issues still exist after changing timezone/DST settings when the options look like they do in the image below.

@Javi thanks, my time settings looked like yours yesterday but I was an hour out.

So I changed my location to Regina to adjust the time offset.

I just tried to change it back to Calgary using the drop down but it's locked on Regina and won't change. The drag and drop works, so my setting is back on Calgary.

Unfortunately I'm still an hour out. I did reboot, but no change.

Calgary is in Alberta and has moved to permanent DST. Perhaps a new rule is required?

It is currently 7:20am

I am having the same issue. I live just outside of Calgary. I opened a ticket for this yesterday. I was told to use eisy-ui and click the "i" and select "Off" under the DST Rule and then adjust the Time Zone Offset manually. I did this:

However, after clicking save the incorrect time was displayed still (one hour behind):

When I clicked on the "i" again it had reverted to UCT -7:

Its frustrating when there are so many time of day programs running.

@K-bert What worked for me.

Select the Regina timezone which is another way to select CST -6.

Enter Calgary's lat and long and DST Rule off.

Used the process on two different Eisy and they set properly with correct time and sunrise/sunset.

Coincidentally I live in Calgary so see below.

Must update firmware if Time Zone Offset is shown.

FYI (after firmware update): If moving the TimeZone does not stick try moving the location pin slightly outside of the city, if the lat/long match the timzone setting exactly it will reset itself.

This worked! It took two tries for each step (setting location to Regina to get time, and entering my lat/long to get sunrise and sunset times).

I work in Calgary, but I live in Cochrane.

Close enough! I found dragging the location pin works really well.

This will be coming to Ontario some year soon. Applied and approved in 2020 but some board is waiting for Quebec and NY to co-operate also.

I think parts of northern Ontario moved already, so it’s coming.

West of Thunder Bay was always Central Time along with Manitoba but still switched back to standard.

An example of being past the logical time zone boundary..... Neighbours, previously from Thunder Bay, complained about putting the kids to bed at 10:00 PM while the sun was still shining on their beds.
