Units are seconds since 1970., unitsseconds

In the actual development process of Android, we often encounter a date in seconds. In this case, we can format them as needed. The specific steps are as follows:

LongSeconds = Long.ParseLong("1405889699580 ");

Date date =NewDate (seconds );

SimpleDateFormatsdf =NewSimpleDateFormat ("MM mm dd, yyyy hh MM ss seconds ");

String time = sdf. format (date ));

Conversion Result: time:, January 1, July 20, 2014

Application scenarios:

When obtaining Android media file date, short message date, and other information, the returned time is the Units are seconds time. This is the format in which we can format the seconds into years, months, days, minutes, and seconds.
