Get Time in Milliseconds Without an Installing an Extra Package

Get time in milliseconds without an installing an extra package?

Time::HiRes has been part of the core since Perl 5.7.3. To check for its availability, check for the Perl version, perl -v, or try to use it with perl -e 'use Time::HiRes;', both from the command line.

Sample usage:

use Time::HiRes qw/ time sleep /;

my $start = time;
sleep rand(10)/3;
my $end   = time;

print 'Slept for ', ( $end - $start ) , "\n";

To build on Konerak's comment, if it isn't there or it cannot be used, use native Linux commands via backticks:

sub time_since_epoch { return `date +%s.%N` }

print time_since_epoch;

Command to get time in milliseconds

date +%s%N returns the number of seconds + current nanoseconds.

Therefore, echo $(($(date +%s%N)/1000000)) is what you need.

Example:

$ echo $(($(date +%s%N)/1000000))
1535546718115

date +%s returns the number of seconds since the epoch, if that's useful.

How get the time in milliseconds in FreeBSD?

Use gettimeofday(), for example:

#include <stdio.h>
#include <sys/time.h>
int main(void)
{
  struct timeval time_now;
    gettimeofday(&time_now,NULL);
    printf ("%ld secs, %ld usecs\n",time_now.tv_sec,time_now.tv_usec);

    return 0;
}

using timspan get only time without millisecond from datetime

You can use a fact, that TimeSpan(Int32, Int32, Int32) can take more then 60 as seconds parameter value:

Dim rtime As New TimeSpan(0, 0, CInt(requestddate.TimeOfDay.TotalSeconds))

Lua - Current time in milliseconds

In standard C lua, no. You will have to settle for seconds, unless you are willing to modify the lua interpreter yourself to have os.time use the resolution you want. That may be unacceptable, however, if you are writing code for other people to run on their own and not something like a web application where you have full control of the environment.

Edit: another option is to write your own small DLL in C that extends lua with a new function that would give you the values you want, and require that dll be distributed with your code to whomever is going to be using it.

iPhone: How to get current milliseconds?

[[NSDate date] timeIntervalSince1970];

It returns the number of seconds since epoch as a double. I'm almost sure you can access the milliseconds from the fractional part.

How to retrieve dateTime with milliseconds from Excel 2010 with XLConnect

I've logged and fixed issue 13 on our github repository at https://github.com/miraisolutions/xlconnect. Milliseconds should now come across. Just make sure you also set options(digits.secs = 3) before printing as otherwise milliseconds won't be displayed.
