Setting TimeZone of Java Calendar to device timezone?

Question

How can I construct a Calendar object using getInstance(TimeZone) to use the device's TimeZone?

Answer 1

According to this issue, just using:

Calendar calendar = Calendar.getInstance();

will give you an instance in the user's default time zone (as per their settings). You can determine the time zone from the calendar with:

TimeZone zone = calendar.getTimeZone();

Other posts have suggested that using TimeZone.getDefault() does not give this user-default time zone - I don't know about that personally, but it's another option to look into.
