Processing based on time zone

[mahalakshme]

Steps:

• Login to maha@cd, prerelease env
• and do School Monitoring encounters for 'ABC Vidhyalaya'
• All dates times are converted to/displayed in IST from UTC in the db - when we do console.log in a rule or in mobile app UI, it is the IST datetime that displays.
• In prod env, Cini - visit schedule rule for the above encounter type has 6 hours added thinking the UTC to IST conversion is not done at product level

AC:

• Identify where the above conversion is made.

Need:

The above is needed because as per the implementation team, the conversion doesn't happen. Identifying where we are doing the above, will help us to identify if any edge cases exist, that needs to be fixed.

Old: Ignore

Have a configuration - of country somewhere

Inputs:

• default report cards, VSR
• Region in Account
• search filter
• audit fields
• API?
• which screen?
• account admin - not useful but used
• get the timezone from mobile app - is the timezone in mobile app reliable?
• CK sitting in US

our dates are like "2024-03-23T06:08:45.000Z" in the offline db. Using Z in the timestamp means UTC. When we display the date using console.log we are shown the date in human friendly timezone converted format. Check this link for more on date being initialised with string - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date#date_time_string_format

There is no issue in Avni mobile wrt to date being in UTC

• The dates present in UTC in the offline db, when instantiated using new Date they all represent same global instant of time.
• Even this prints out moment(new Date("2024-08-31T18:30:00.000Z")).format("MMMM") gives out correct month which is September.
• all moment manipulation like adding months etc are all correct.

@petmongrels where is the conversion happening? How does it know it needs to convert to IST?

[petmongrels]

The timezone comes from the JS runtime environment. It is just the display that is changed.
We can use sensors feature to test this out. Same date will be shown differently by changing the geolocation - https://www.youtube.com/watch?v=pIpN_AuV4AI
