If you use anything else besides the frontend to talk to HA, make sure it handles it differently. The methods sun.next_rising(hass) and sun.next_setting(hass) are backwards compatible, just be careful if you used to read the raw attributes. Prior to 1972, this time was called Greenwich Mean Time (GMT) but is now referred to as Coordinated Universal Time or Universal Time Coordinated (UTC). the sun attributes for rising and setting are now in UTC.Python does not allow comparing a naive with an aware datetime object. ack_time_change and ack_point_in_time will now return a time zone aware datetime object.The following list is only for people that run custom components: Backwards incompatible stuffĪll built-in components have been upgraded.

So you see, you have several HF frequencies from which to choose to get the 'correct' UTC time using your general coverage receiver. CHU broadcasts continuously on 3.330, 7.335, and 14.670 MHz, also AM as with WWV and WWVH. This information is currently not used but can prove useful in the future when we start analyzing the historical data. It transmits time signals and voice announcements from Ottawa, Ontario. This refactor adds a new migration for the database adding a utc_offset column to events and states. The usage of the old methods have not changed and should be backwards compatible. The old ack_time_change and ack_point_in_time use now internally two new methods: ack_utc_time_change and ack_point_in_utc_time.
#Utc clock zone code
The changes to the code are mostly backwards compatible. Homeassistant : time_zone : America/Los_Angeles Compatibility You can find a list of compatible time zones on Wikipedia. If you have no time zone setup, it will be auto detected using the existing detection code using. Setting up a time zone happens in configuration.yaml. Local times should only be used for user facing information: logs, frontend and automation settings in configuration.yaml.

Local time is based on the time zone that you have setup in your configuration.yaml. There is also such a thing as local time.

is a new util package with date helpers. Knowing this and using the time zone map, it’s much easier to figure out the exact time around. Equally, looking East, you’ll notice the countries are in UTC+ offset. This is a timezone aware UTC datetime object. The time zone map illustrates this very clearly: if you locate the Greenwich meridian and look at the regions and countries located West of it, you’ll see UTC- time offsets. To get the current time in UTC you can call .utcnow(). The code has been live in the dev branch for the last 9 days and will be soon released to the master branch.įrom now on all internal communication will be done in UTC: time changed events, datetime attributes of states, etc. I’ve added some extra test coverage to time sensitive parts to ensure stability. I have recently merged code to refactor Home Assistant to use only UTC times internally.
