The following summarizes the implementation methods for obtaining a specified date in Java. For more information, seeCopy codeThe Code is as follows:Format a Date String --> Date or Data --> String SimpleDateFormat sdf = new SimpleDateFormat

Format Date string-->date or data-->stringSimpleDateFormat SDF = new SimpleDateFormat ("Yyyy-mm-dd");Date date = Sdf.parse ("2009-11-04");//string-->dateString sdate = Sdf.format (date);//Data-->string ================================================

Java get millisecond: system. currenttimemillis () Java get nanosecond: system. nanotime () (used to get very accurate time, recommended !) Java obtains the current date: gregoriancalendar date_1 = (gregoriancalendar) calendar. getinstance (); Java.

Today we see in PHP to calculate the time difference between two times, the following we directly use the Data,strtotime and three functions are implemented, there is a need for friends to refer to. This is the example that needs to be told today.
