Affected Areas and Manually Tested Areas

Important

Adds timezone management with context provider, browser fallback, and local storage, updating components to reflect timezone changes.

• Timezone Management:
  • Introduces TimezoneProvider in providers/Timezone.tsx to manage timezone context.
  • Fallback to browser timezone if no preferred timezone is set.
  • Stores preferred timezone in local storage (LOCALSTORAGE.PREFERRED_TIMEZONE).
• Component Updates:
  • CustomTimePicker.tsx, CustomTimePickerPopoverContent.tsx, and TimezonePicker.tsx now use useTimezone hook to access timezone context.
  • TimezoneAdaptation.tsx allows clearing timezone override, reverting to browser timezone.
• UI Changes:
  • Displays active timezone offset in CustomTimePicker and CustomTimePickerPopoverContent.
  • Adds "Clear override" button in TimezoneAdaptation when timezone is overridden.

  Storing the timezone as a JSON string in localStorage is inconsistent with how it's retrieved. Consider storing it as a plain string instead.

• Draft comment:
  Avoid using the component/index.tsx file structure approach, as it makes it difficult to debug and find components using global search tools like VS Code.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable:
  The comment is not relevant to the changes made in this diff. The file structure mentioned in the comment does not apply to the file being reviewed. Therefore, the comment should be deleted.
  I might be missing some context about the overall project structure, but based on the file path and name, the comment does not seem applicable.
  The file path and name provide enough context to determine that the comment is not relevant to this specific file.
  The comment is not about a change made in this diff and should be deleted.
