3. Timezone sharing ability - Sending and receiving timezone logic implementation

[tomastiminskas]

Implement logic to send current timezone when updated on specific chat and receive/store timezone on each chat.

Base branch: develop: All new changes needs to be done using develop branch as base branch. We use develop as base for Test Flight distribution releases

Context

When sending a message we use the Sphinx.send method. This method contains a msgJson param that will contain a json string with all message content including text, mediaKey (if attachment), amount (if boost), etc. This msgJson param now contains a new key metadata that can store and send any json string. We will use this metadata json to send timezone. When a message is received the msgJson sent by the msg sender is decoded using the Mappable class MessageInnerContent inside the init method of GenericIncomingMessage.

Requirements

MODELS

• Add metadata field in MessageInnerContent struct

NEW TIMEZONE FORM

• Implement logic to show value of timezoneEnabled for specific chat in new view toggle control
• Implement logic to show value of timezoneIdentifier for specific chat in new view field (show Use Computer Settings if NULL)
• Implement logic to store new values on chat when modified on new view form:
  • Save timezoneEnabled if toggle changed (TRUE/FALSE)
  • Save timezoneIdentifier from picker value if changed (Set to NULL if first option "Use Computer Settings" is selected from picker)
  • Update timezoneUpdated to TRUE when timezoneIdentifier value changes

SENDING TIMEZONE

• Send json string with timezone inside metadata attribute (msg["metadata"] = "{\"timezone\": \"America/Los_Angeles\"}") on message (inside func formatMsg()) if timezoneEnabled == true and timezoneUpdated == true on the chat you are sending the message.
• Set timezoneUpdated = false after message with timezoneIdentifier is sent (this will prevent timezone to be sent on every message if it doesn't changed)

RECEIVING TIMEZONE

• Add timezone attribute in GenericIncomingMessage and save it inside innerContent.metaData if not empty.
• Save remoteTimezoneIdentifier (coming as timezone inside metadata json) on chat when message is received in a contact conversation (chat.remoteTimezoneIdentifier) and on message when received in a tribe (message.remoteTimezoneIdentifier)

Acceptance Criteria

• Implement logic to set timezone sharing for each contact/tribe, send it on message and receive store timezone information coming from others on incoming messages
