Python conversion implementation code for time between various languages

a basic knowledge

Millisecond MS
Microsecond μs
Nanosecond nanoseconds
1 sec =1000 msec 1 msec =1000 microseconds 1 μs =1000 nanoseconds

Two Perl

In Perl, you can use time or localtime to get the times, the number of seconds to return from 0 o'clock January 1, 1970, localtime to return a string representation of the current time, or a tuple representation of a month or date.

#!/usr/bin/perluse strict;use warnings;use POSIX qw (strftime); # seconds from 1970.01.01 00:00:00my $ti = time ();p rint $ti; print "\ n";p rint strftime ("%y-%m-%d%h:%m:%s\n", LocalTime ($ti)), #1310623469 #2011-07-14 14:03:58my $t = localtime (); Print $t;p rint "\ n"; #Thu Jul 12:25:16 2011my ($sec, $min, $hour, $mday, $mon, $year, $wday, $yday, $ISDST) =localtime (); Print $year;p rint "\ n"; #111print strftime ("%y-%m-%d%h:%m:%s\n", localtime ()); #2011-07-14 12:26:01

Three C #
1tick = nanosecond

using system;using system.collections.generic;using system.linq;using System.Text;      Namespace mytest{class Program {static void Datetimetest () {DateTime DT2 = DateTime.Now; Console.WriteLine (DT2.      Ticks); Console.WriteLine (DT2.    ToString ("mm/dd/yyyy hh:mm:ss")); } static DateTime?      Convertperltimetodatetime (String perltime) {DateTime? dt = null;      Perl time variable:seconds from 1970.01.01 00:00:00 string SDT = Perltime;      Long Ldt = 0; if (long. TryParse (SDT, out Ldt)) {Long ldt2 = new DateTime (1970, 1, 1).         Ticks + LDT * 1000 * 1000 * 10;        DT = new DateTime (LDT2, datetimekind.local); Console.WriteLine (dt.      Value.tostring ("mm/dd/yyyy hh:mm:ss"));    } return DT;      } static void Main (string[] args) {datetimetest ();      Convertperltimetodatetime ("1309423883"); 634462479788396720//07/14/2011 01:46:18//06/30/2011 08:51:23}} 

Four Python

Python is similar to Perl, and time is the number of seconds starting January 1, 1970.

Import timeisotimeformat= '%y-%m-%d%x ' # seconds from 1970.01.01 00:00:00t = Time.time () print (t) print time.strftime ( Isotimeformat,time.localtime (t)) #1310623143.12#2011-07-14 13:59:03 (YEAR,MON,DAY,HOUR,MIN,SEC,WDAY,YDAY,ISDST) = Time.localtime () print (year) print (Time.strftime (Isotimeformat, Time.localtime ())) #2011 #2011-07-14 13:59:03
