Known Direct Subclasses |
A specific moment in time, with millisecond precision. Values typically come
from currentTimeMillis()
, and are always UTC, regardless of the
system's time zone. This is often called "Unix time" or "epoch time".
Instances of this class are suitable for comparison, but little else.
Use DateFormat
to format a Date
for display to a human.
Use Calendar
to break down a Date
if you need to extract fields such
as the current month or day of week, or to construct a Date
from a broken-down
time. That is: this class' deprecated display-related functionality is now provided
by DateFormat
, and this class' deprecated computational functionality is
now provided by Calendar
. Both of these other classes (and their subclasses)
allow you to interpret a Date
in a given time zone.
Note that, surprisingly, instances of this class are mutable.

locale are used. If you need control over the time zone or locale,
use SimpleDateFormat
instead.
