convertTimezones
Converts a date time string from one timezone to another.
- The date time string must follow luxon date-time format: yyyy-MM-dd hh:mm:ss a. Example: 2025-06-16 10:00:00 pm.
- The timezones must be valid IANA timezones. Example: Asia/Calcutta, America/New_York.
- You must first invoke the tool named "currentDateTimeAndTimezone" to get the current date, time and timezone of the user if they don't specify the date or time explicitly or use relative date or time (i.e. in an hour/today/tomorrow/yesterday/next week/next month/next year etc.).
