Use local time of Home Assistant rather than browser. about clock-weather-card

[pkissling]

Can’t you use the time zone setting as set in HA? I have the same issue since I work on a different continent from where my house is.

thanks for the hint. that might be feasible and might make the configuration/implementation easier.
i'll have a look into it in the next couple of days

If it doesn't add too much complexity, I'd love the ability to specify any sensor for the date/time. I have a wall panel where I'd like to display the time and weather in different cities where I have family. I can currently do this with the weather since I can specify any sensor, but I can't for the time.

[pkissling]

thanks for the request.
when i initially implemented the card, i realised that sensor.time is optional in home assistant and must be configured explicitly.
hence i could not rely on the sensor being available in every HA instance. thus i decided to get the time from the current browser.

what i could do though, is to allow providing an optional property time_sensor: sensor.time and read the current time from there. but since sensor.time only holds the time, i would additionally need sensor.date to show the weekday and the corresponding date, which makes the configuration a bit clunky since a user would have to configure both values time_sensor and date_sensor to make it work. and if a user only configures either property, the card will not work properly

Much prefer the suggestion to use any sensor - this allows more flexibility. Is there a way to have a default that can be overridden?

[miholobolo]

I would love to have this as well. In my case i use the clock on a screen device that is cut from the internet, and has no reliable internal clock. I was hoping that could use the time of the HA.

[dunxd]

It's odd that sensor.time is not enabled by default in HA, but anyway...

I see how it makes the config a bit clunky. Can you set defaults so if either time_sensor or date_sensor were missing something would still be displayed?

I use LibreWolf Browser which only uses GMT 0. I would really like an an option to define a custom offset or timezone

(get browser time zone, calculate difference to user setting and set new time)

[teddy-ptmedia]

I also would like to be able to set my home time zone for the same reasons. I’m away from home and my HA should show the time at my home and not my local time where I am offsite.

@pkissling any development on this? Would really appreciate to have the host machine local time option. :) Thank you so much for this card!

i currently use this userscript with e.g. violentmonkey:

change YOUR_DOMAIN and germanTimeZoneOffset

// ==UserScript==
// @name         Deutsche Zeitzone
// @namespace   Violentmonkey Scripts
// @match       https://YOUR_DOMAIN
// @version      0.1
// @description  Überschreibt das Date-Objekt, um die deutsche Zeitzone zu verwenden
// @author       Me
// @grant        none
// @run-at       document-start
// ==/UserScript==

(function() {
    'use strict';

    const today = new Date();
    const month = today.getMonth() + 1; // Januar ist 0, daher +1
    const day = today.getDate();
    const hour = today.getHours();

    let isSummerTime;

    if (month > 3 && month < 10) { // Sommerzeit gilt von April bis September
      isSummerTime = true;
    } else if (month === 3 && day >= 29 && hour >= 2) { // letzter Sonntag im März um 2 Uhr
      isSummerTime = true;
    } else if (month === 10 && day <= 25 && hour < 3) { // letzter Sonntag im Oktober um 3 Uhr
      isSummerTime = true;
    } else {
      isSummerTime = false;
    }

    const germanTimeZoneOffset = isSummerTime ? -120 : -60; // Deutsche Zeitzone ist UTC+1 (+2 während Sommerzeit)
    const originalDate = Date;

    function getGermanDate(...args) {
        if (args.length === 0) {
            const now = new originalDate();
            return new originalDate(now.getTime() + (now.getTimezoneOffset() - germanTimeZoneOffset) * 60000);
        } else {
            return new originalDate(...args);
        }
    }

    // Überschreibe das Date-Objekt
    const newDate = function(...args) {
        return getGermanDate(...args);
    };

    // Kopiere die Prototypen und statischen Methoden
    Object.setPrototypeOf(newDate, originalDate);
    Object.setPrototypeOf(newDate.prototype, originalDate.prototype);
    for (const prop of Object.getOwnPropertyNames(originalDate)) {
        if (typeof originalDate[prop] === 'function') {
            newDate[prop] = originalDate[prop].bind(originalDate);
        } else {
            Object.defineProperty(newDate, prop, Object.getOwnPropertyDescriptor(originalDate, prop));
        }
    }

    // Date-Objekt überschreiben
    Date = newDate;
    window.Date = newDate;
})();

i did the code changes today (introducing an attribute use_browser_time which can be set to false to use time from time_zone configured in HA.
i will have to do some testing tomorrow and will afterwards release a new version

#177

@dunxd @rad2000 if you want a feature to configure a dedicated time and date sensor, feel free to create a new issue 👍🏻

[pedromfa]

@pkissling thank you so much! 😎

[pedromfa]

Hi again. Now it seems there's a 12h difference between Ha time and the one your card displays. See screenshot attached. Perhaps some error in the background? Appreciated the efforts here @pkissling. 😎😉

[teddy-ptmedia]

Is it 12hr or is one showing 12hr and one showing 24hr formats?On Apr 23, 2023, at 3:44 PM, pedromfa ***@***.***> wrote: Hi again.

Both time format gives me the wrong time by +12h

Can you please give additional information?
Your current time zone (browser), your current time, the time zone configured in HA and the browser you are using. i want to try to reproduce the problem

[pedromfa]

My current time zone is UTC+7 (12:42lt). My HA host is UTC+1(0642lt). The card shoud be showing 0642lt but it's showing 1842lt. And I'm using the android companion app to access my instance. Sorry for all this trouble. 😁

[pkissling]

What time zone is configured in your HA instance? e.g. time_zone: Europe/Berlin

Just updated after getting back from my holiday, but tested by changing the timezone on my phone. Works as expected which is awesome. Am I right in thinking you achieved this by applying the timezone for HA to the time coming from the browser?

IMHO use_browser_time should be false by default as it should correspond to the location that weather is being shown for in the same card!

yes, agreed. i have this on the radar for the next major version of the card. by default the card would then fetch the current time from HA instead of the browser and a user would be able to disable it by setting use_browser_time: false.

the reason i didn't do this in the current release is because i did not want to break existing dashboards by changing the default logic of where the card gets the time from

[pkissling]

thanks for the feedback. i released 1.0.15 today. hope its fixed now. otherwise please open a new issue

[pedromfa]

@pkissling it's wonderful after last update! Many many thanks for this! 😎
