In my application I need to convert data to location times. I have java Date and TimeZoneId

When I get data from service – it comes in as UTC and I get time zone as well. Need to convert into that time zone’s time. Function I created:

 private static Date getDateConvertedToTimeZone(Date utcDate, String timeZoneId)
    {
        TimeZone timeZone = TimeZone.getTimeZone(timeZoneId);
        if (timeZone.getID().equalsIgnoreCase(timeZoneId))
        {
            Log.d(LOG_TAG, "Good: " + timeZoneId + " " + Long.toString(utcDate.getTime()));
            return new Date(utcDate.getTime() + timeZone.getRawOffset() + (timeZone.inDaylightTime(utcDate) ? timeZone.getDSTSavings() : 0));
        }

        Log.d(LOG_TAG, "Bad?: " + timeZoneId + " " + Long.toString(utcDate.getTime()));
        LogData.d(LOG_TAG, "getDateConvertedToTimeZone bad time zone: " + timeZoneId, LogData.Priority.None);
        return utcDate;

    }

Simple? Right. Just grab time zone by ID and do some math on Date object. This is what I thought… When I parse data function called repeatedly and here is output:

Are you using 3 letter time zone identifiers ? This is not supported in Andorid.

See Documentation

Other than the special cases “UTC” and “GMT” (which are synonymous in this context, both corresponding to UTC), Android does not support the deprecated three-letter time zone IDs used in Java 1.1.

you’re expected to use

Olson name of the form Area/Location, such as America/Los_Angeles. The
getAvailableIDs() method returns the supported names.

You also can use the GMT+05:00 syntax.
