This project is a proving ground for possible future additions to java.time. The ThreeTen-Extra project extends java.time with additional classes. For earlier Android (Later versions of Android bundle implementations of the java.time classes.Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.Java 9 adds some minor features and fixes.Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.No need for strings, no need for java.sql.* classes. Use a JDBC driver compliant with JDBC 4.2 or later. You may exchange java.time objects directly with your database. And search Stack Overflow for many examples and explanations. The Joda-Time project, now in maintenance mode, advises migration to the java.time classes. These classes supplant the troublesome old legacy date-time classes such as, Calendar, & SimpleDateFormat. The java.time framework is built into Java 8 and later. For other formats, search Stack Overflow to learn about DateTimeFormatter. Precision and representation Software timekeeping systems vary widely in the precision of time measurement (granularity) some systems may use time units as large as a day, while others may use nanoseconds. To get a String representing this date-time value, call Instant::toString. 1 Computing epochs are nearly always specified as midnight Universal Time on some particular date. Instant instant = Instant.ofEpochSecond( mnSeconds, mnNanoseconds ) Or pass both numbers to the of, as two arguments. Instant instant = Instant.ofEpochSecond( mnSeconds ).plusNanos( mnNanoseconds ) The Instant class represents a moment on the timeline in UTC with a resolution up to nanoseconds. The Joda-Time team also advises migration to java.time. ![]() These classes supplant the old troublesome date-time classes such as. replace "Z", "" ) // Remove the `Z` on the end (indicating UTC). replace( "T", " " ) // Replace the `T` in the middle with a SPACE. toString() // Generate text representing this `Instant` object in standard ISO 8601 format. Returns another `Instant` object, per Immutable Objects pattern. plusNanos( mnNanoseconds ) // Add on a fractional second as a count of nanoseconds. ofEpochSecond( mnSeconds ) // Determine a moment from a count of whole seconds since the Unix epoch of the first moment of 1970 in UTC (T00:00Z). Tl dr Instant // Represent a moment in UTC. ![]()
