Examples of java.util.TimeZone.useDaylightTime()

java.util.TimeZone.useDaylightTime()
Queries if this time zone uses daylight savings time.
If an underlying TimeZone implementation subclass supports historical Daylight Saving Time schedule changes, the method refers to the latest Daylight Saving Time schedule information. @return true if this time zone uses daylight savings time,false, otherwise.
