Unix Timestamp → Beijing Time
Beijing Time → Unix Timestamp
The Unix Timestamp Conversion Tool can convert Unix timestamps into standard formatted Beijing time and also convert standard formatted Beijing time into a Unix timestamp;
What is a Unix timestamp: A timestamp refers to the total number of seconds from 00:00:00 (GMT) on January 1, 1970 (08:00:00 Beijing time on January 1, 1970) to the current time.
PHP Example Usage of Unixtime:
Get the current timestamp: $time = time(); Convert to Beijing time: $datetime = date('Y-m-d H:i:s',$time); Convert to timestamp: $unixtime = strtotime($datetime); (www.pcjson.com)

| MySQL | SELECT unix_timestamp(now()) |
| Perl | time |
| PostgreSQL | SELECT extract(time FROM now()) |
| Python | First, import time, then time.time() |
| Ruby | To get the Unix timestamp: Time.now or Time.new To display the Unix timestamp: Time.now.to_i |
