Unix timestamp → Beijing time
Beijing time → Unix timestamp
The Unix timestamp conversion tool can convert Unix timestamps to standard Beijing time, and also convert standard Beijing time to Unix timestamps.
What is a Unix timestamp: A timestamp is the total number of seconds from 00:00:00 on January 1, 1970, Greenwich Mean Time (08:00:00 on January 1, 1970, Beijing time) to the present.
PHP example of using Unix timestamp：
Get 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）
