Introduction to Unix Timestamp Conversion Tool

Unix timestamp conversion tool, which can convert Unix timestamp into Beijing time in standard format, and convert Beijing time in standard format into UNIX timestamp;

What is Unix timestamp (Unix timestamp): Timestamp refers to the time from January 01, 1970, 00:00:00 GMT (Beijing time, January 1, 1970, 08:00:00) The total number of seconds so far.

Use of PHP example 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)

1. How to obtain the current Unix timestamp (Unix timestamp) in different programming languages or databases:

PHP time()
Java time
JavaScript Math. round(new Date(). getTime()/1000)
getTime() returns the value in milliseconds
.NET / C# time = (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000
MySQL SELECT unix_timestamp(now())
Perl time
PostgreSQL SELECT extract(time FROM now())
Python import time first and then time.time()
Ruby Get Unix timestamp: Time.now or Time.new
Display Unix timestamp: Time.now.to_i
SQL Server SELECT DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE())
Unix / Linux date +%s
VBScript / ASP DateDiff("s", "01/01/1970 00:00:00", Now())

2. In different programming languages or databases, realize common time → Unix timestamp:

PHP mktime(hour, minute, second, day, month, year)
Java long datetime = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").parse("01/01/1970 01:00:00");
JavaScript var commonTime = new Date(Date.UTC(year, month - 1, day, hour, minute, second))
MySQL SELECT unix_timestamp(time)
Perl 先 use Time::Local 然后 my $time = timelocal($sec, $min, $hour, $day, $month, $year);
PostgreSQL SELECT extract(datetime FROM date('YYYY-MM-DD HH:MM:SS'));
Python 先 import time 然后 int(time.mktime(time.strptime('YYYY-MM-DD HH:MM:SS', '%Y-%m-%d %H:%M:%S')))
Ruby Time.local(year, month, day, hour, minute, second)
SQL Server SELECT DATEDIFF(s, '1970-01-01 00:00:00', datetime)
Unix / Linux date +%s -d"Jan 1, 1970 00:00:01"
VBScript / ASP DateDiff("s", "01/01/1970 00:00:00", datetime)

3. In different programming languages or databases, Unix timestamp (Unix timestamp) is converted to ordinary time (year-month-day hour:minute:second):

PHP date('r', Unix timestamp)
Java String datetime = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(new java.util.Date(Unix timestamp * 1000))
JavaScript 先 var unixTimestamp = new Date(Unix timestamp * 1000) 然后 commonTime = unixTimestamp.toLocaleString()
Linux date -d @Unix timestamp
MySQL from_unixtime(Unix timestamp)
Perl 先 my $time = Unix timestamp 然后 my ($sec, $min, $hour, $day, $month, $year) = (localtime($time))[0,1,2,3,4,5,6]
PostgreSQL SELECT TIMESTAMP WITH TIME ZONE 'time' + Unix timestamp) * INTERVAL '1 second';
Python 先 import time 然后 time.gmtime(Unix timestamp)
Ruby Time.at(Unix timestamp)
SQL Server DATEADD(s, Unix timestamp, '1970-01-01 00:00:00')
VBScript / ASP DateAdd("s", Unix timestamp, "01/01/1970 00:00:00")
