Calendar IO

Hi,

I am not able to retrieve data using the readCalendar() function in case the timezone in the calendar is set to the IST time zone value.

Any help would be appreciated.

Hi, 

From the stacktrace you can see that the error is at java level, java is saying IST isd an unknow time zone id

TimeZone is not the same as ZoneId.... documentation: "The default set of data is supplied by the IANA Time Zone Database (TZDB). This has region IDs of the form '{area}/{city}', such as 'Europe/Paris' or 'America/New_York'."

It depends on what you mean by IST. For example ZoneId.of("Europe/Dublin") for Irish Summer Time, ZoneId.of("Asia/Tel_Aviv") for Israel Standard TIme or ZoneId.of("Asia/Kolkata") for India Standard Time.

hope this help
