Java Get UNIX Timestamp

The UNIX timestamp is the number of seconds that have elapsed since the start of the January 1, 1970 (Midnight of Utc/gmt), regardless of the leap seconds.

In most Unix systems, the UNIX timestamp is stored as 32 bits, which raises the 2038 issue.

However, because the requirement is a UNIX timestamp that requires an int type. That's how I designed it at first.

/** * Gets the current event unxi timestamp * @return */public static int Getunixtimestamp () {long Rest=system.currenttimemillis ()/1000l;return ( int) rest;}

New encapsulation of some methods. The following stability is much better.
