Instant instant = Instant.now() // Current moment in UTC.Īpply a time zone ( ZoneId) to get a ZonedDateTime. These new classes are inspired by the highly successful Joda-Time project, defined by JSR 310, and extended by the ThreeTen-Extra project.Īn Instant is a moment on the timeline in UTC with resolution up to nanoseconds.

Android: Use this wrapped version of that backport.

Java 7 & 6: Use the backport of java.time.

Java 8 and later: The java.time framework is built-in.

Those old classes have been supplanted by the java.time framework. The old date-time classes have proven to be poorly designed, confusing, and troublesome. The other answers, while correct, are outdated. …or… ZonedDateTime.now( ZoneId.of( "America/Montreal" ) ) // In a particular time zone Tl dr Instant.now() // Current moment in UTC. Much of theįormatting / parsing assumes ASCII text and is therefore not suitable 1, or 1 second before 1st Jan 1970 UTC).

Time that was skipped due to a DST transition, will result in a date SwitchTimezone(String) on a date that cannot exist, such as a wall This behavior it may change in the future. Wikipedia article on the Year 2038 problem for details. The reliable time range representable from 1902 until 2037.See the This class has a number of issues and it is recommended thatįor historical reasons when performing time calculations allĪrithmetic currently takes place using 32-bit integers. See class for all the details.Īs many people are pointing out, Google says this class has a number of issues and is not supposed to be used anymore: tText(today.format("%k:%M:%S")) // Current time Then, you can get all the date fields you want, like, for example: tText(today.monthDay + "") // Day of the month (1-31)

Time today = new Time(Time.getCurrentTimezone())

The resulting sequence will repeat the same value, such as 1410543204000, until the next second has started, at which time 1410543205000 will begin to repeat.Īctually, it's safer to set the current timezone set on the device with Time.getCurrentTimezone(), or else you will get the current time in UTC. do something that takes more than one millisecond, but less than one second. Log.d("TIME TEST", Long.toString(time.toMillis(false))) If in a loop you do Time time = new Time() tToNow() The time value is only precise to one second the milliseconds portion is always 000. NOTE 2: Even though the Time class has a toMillis(ignoreDaylightSavings) method, this is merely a convenience to pass to methods that expect time in milliseconds. "his class has a number of issues and it is recommended that GregorianCalendar is used instead". It's been several years since I wrote this answer,Īnd it is about an old, Android-specific and now deprecated class. You can ( but no longer should - see below!) use : Time now = new Time()
