How to Customize Time Zones for Java's `java.util.Date` Parsing?

Customizing Time Zone for Java Util Date

Parsed dates from strings using java.util.Date may adopt the time zone of the local environment. When the time zone information is not included in the parsed data, we often need to set a specific time zone for the date object. This article explores how to customize the time zone using DateFormat.

Solution: Using DateFormat

java.text.DateFormat enables the manipulation of dates based on specified time zones. To set a time zone for a Date object:

1. Create a SimpleDateFormat instance.

   SimpleDateFormat isoFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");

2. Set the time zone using setTimeZone(TimeZone).

   isoFormat.setTimeZone(TimeZone.getTimeZone("UTC"));

3. Parse the date using the formatted.

   Date date = isoFormat.parse("2010-05-23T09:01:02");

By using this approach, you can assign a specific time zone to your Date object, regardless of the time zone of the source string.
