Java supports three timezone constants for Eastern Standard Time i.e. 'EST'
, 'America/New_York'
and 'EST5EDT'
. It is very important to understand difference between them to correctly utilize these constants for converting date or time in Eastern Standard Time
values.
In eastern part of the USA, timezone offsets are different during summer and winter.
