I honestly cannot believe that this is not a question yet on Code Golf, but....

Print the local time (with a.m. or p.m.) as a string to the console, preceded by "It's ".

Example:

Run code....

Output:

It's 12:32p.m.

Shortest code wins.

Code away!

Bash, 39 33 bytes

date "+It's %I:%M%P."|sed s/m/.m/

Wasted a bunch of chars because the spec requires a.m. or p.m. while date outputs am or pm. Thanks to @DigitalTrauma for saving 6 bytes!

This might not be very portable. It works on Ubuntu 15.04.

AppleScript, 198

Because AppleScript. Because why not:

set AppleScript's text item delimiters to {":"," "}
set d to (current date)'s time string's every text item
"It's "&d's item 1&":"&d's item 2&string id ((d's item 4's first character's id)+32)&".m."

That was painful.

PHP, 35 33 bytes

Using the wrong tool for the job!

It's <?=trim(date('h:ia'),m)?>.m.

It simply removes the m at the end of am or pm, to allow to add the dots. The date comes as 00:00am, and with trim it becomes 00:00a.


Old answer (PHP 5.4+ only):

It's <?=date('h:i'),date(a)[0]?>.m.

This works because you can de-reference a value returned from a function. This isn't possible in PHP5.3 or older.

You can try it online!

The time() function returns the current time. When passed to strftime with the format %I:%M%P, this results in HH:MMam/pm, where the hours are per a 12-hour clock. We back up one character with \b to remove the m, leaving a trailing a or p, then tack .m. onto the end.

Perl 5.10+, 58 62 bytes

localtime=~/(..)(:..)/;say"It's ",$1%12||12,$2,$1>11?p:a,".m."

Must be run with the -M5.010 command line flag to get say.

I didn't account for a couple of edge cases in my original solution (namely, 00:** and 12:**); fixed at a cost of 4 additional bytes.

How it works

In scalar context, localtime returns a string like this:

Sat Sep 12 03:13:22 2015

The minutes field is already zero-padded, which saves some bytes (in list context, localtime returns numbers instead of strings, so you have to pad them yourself).

Here it is ungolfed:

localtime=~/(..)(:..)/;  # Store hour in $1 and minutes in $2
say"It's ",              # Print "It's " followed by...
   $1%12||12,            # hour in 12-hour format
   $2,                   # minutes
   $1>11?p:a,            # "p" if hour > 11, otherwise "a"
   ".m."'                # ".m."

Perl 5.14+, 57 bytes

(Just for fun, since it stretches the rules a bit.)

say"It's ",(strftime"%l:%M%P",localtime)=~s/m/.m./r

51 bytes + 6 bytes for -MPOSIX. Must also be run with the -M5.010 command line flag to get say.

This solution is dependent on your locale, so will not work on all systems. It also uses the POSIX module, which might be stretching the definition of a "built-in", even though it is a core module.

Perl 5.14+ is required for the non-destructive r modifier to the substitution operator. An equivalent solution that works on 5.10+ is:

$_=strftime"%l:%M%P",localtime;chop;say"It's $_.m."

This is also 57 bytes (51 bytes + 6 bytes for -MPOSIX).

($s,$m,$h)=localtime;printf"It's %d:%02d%s.m.",$h<13?$h:$h%12,$m,$h<12?a:p

Using POSIX: 80 bytes

use POSIX;$_=strftime"It's %I:%Mx.m.",@_=localtime;$x=$_[1]<13?a:p;s/x/$x/;print

Using POSIX with time locale dependence & switches : 54 bytes (48 + 6)

$_=strftime"It's %I:%M%P",localtime;s/m/.m./;say

Test

$ export LC_TIME="en_DK.UTF-8"
$ perl -MPOSIX -M5.01 whatsthetimechap.pl

    \$\begingroup\$ You can save some bytes on your POSIX solutions by using -MPOSIX instead of use POSIX;, dropping the parens in your call to strftime, and replacing print with say (-M5.010 is free).

  • \$\begingroup\$ You don't need to calculate d.length, you could just write -n and it will calculate from the end, just an FYI. d="It's "+new Date().toLocaleTimeString();d.slice(0,-6)+d.slice(-2,-1).toLowerCase()+'.m.' 90 bytes. And you can save one byte by moving the "It's " string. And a few bytes from a little string shortcut in there. d=new Date().toLocaleTimeString();"It's "+d.slice(0,5)+d[9].toLowerCase()+'.m.' 79 bytes. \$\endgroup\$ – Jan Sep 11 '15 at 21:26
  • \$\begingroup\$ And if the answer needs to be locale-independent (as some have posted), just use toLocaleTimeString("en-US") 86 bytes. \$\endgroup\$ – Jan Sep 11 '15 at 21:48

Bash, 44 characters

Pure Bash, just shell builtins, no ***utils.

printf -vt "It's %(%I:%M%P)T"
echo ${t%m}.m.

Sample run:

bash-4.3$ printf -vt "It's %(%I:%M%P)T";echo ${t%m}.m.
It's 01:04p.m.

Powershell, 49 bytes

"It's {0:hh:mm}$("ap"[($d=date).hour/23]).m."-f$d

(date).hour/23 seems to work as an index for "ap" because it rounds to 0 for hours less than 12 and 1 for 12 and above.

\$\endgroup\$
  • \$\begingroup\$ Should be able to golf off a few characters by instead treating the "p"/"a" as string turned into an implicit char-array -- 51 bytes -- "It's $(date -f hh:mm)$("pa"[(date).hour-lt12]).m." \$\endgroup\$ – AdmBorkBork Sep 11 '15 at 13:56
  • \$\begingroup\$ Your latest "{0:hh:mm}$("ap"[($d=date).hour/23]).m."-f$d misses the It's at the beginning. If you tack that onto the front, it's the same 49 bytes as "It's $((date -f hh:mm)+"ap"[(date).hour/23]).m." \$\endgroup\$ – AdmBorkBork Sep 11 '15 at 15:57
  • \$\begingroup\$ My bad. I've fixed it. Anyway, this version is more "correct", as it only makes a single call to date \$\endgroup\$ – Danko Durbić Sep 12 '15 at 5:19
  • \$\begingroup\$ For what it's worth, I stumbled across the following while researching something else. Apparently [datetime] casts are always en-US. That means something like this "It's $(("{0:h:mmt}"-f[datetime](date)).ToLower()).m." is possible ... which, granted, is 54 bytes and longer than your current solution, but still an interesting quirk of the language. \$\endgroup\$ – AdmBorkBork Sep 23 '15 at 19:54
  • \$\begingroup\$ @TimmyD Interesting, but it seems it's only casting to DateTime that's en-US, not formatting. \$\endgroup\$ – Danko Durbić Sep 24 '15 at 9:32

Locale-dependent

For browser environments that have the locale set to en-CA or any locale that outputs a 12-hour time by default:

CoffeeScript, 81 bytes

alert "It's #{(x=(new Date).toLocaleTimeString().toLowerCase())[..4]} #{x[9]}.m."

JavaScript (ES5), 90 bytes

alert("It's "+(x=(new Date).toLocaleTimeString().toLowerCase()).slice(0,5)+' '+x[9]+".m.")

Locale-independent

CoffeeScript, 113 96 bytes

alert "It's #{(h=(d=new Date).getHours())%12}:#{('0'+d.getMinutes())[-2..]} #{'ap'[+(h>11)]}.m."

Previous:

This one works in all browser environments regardless of locale. Requires Chrome 24+, Firefox 29+, IE 11+, Opera 15+ or any derivatives of such. Does not work in Safari. See Intl.DateTimeFormat.

alert "It's #{new Intl.DateTimeFormat('en',{hour:f='2-digit',minute:f}).format(new Date).toLowerCase()[..-2]}.m."

C, 154 bytes

#include <time.h>
#define l localtime(&r)
main(){time_t r=time(0);printf("It's %02i:%02i%c.m.",(l->tm_hour+11)%12+1,l->tm_min,(l->tm_hour>=12)?'p':'a');}

In contrast to the other C answer, this one uses the correct "a.m."/"p.m." format. The other poster omitted #include <time.h> – if your compiler allows this, we get down to 136 bytes. Which one should we count?

Moonscript - 56 bytes

print "It's "..(os.date'%I:%M%p'\gsub 'M','.M.')\lower!

Unfortunately the Lua standard library only implements %p for uppercase AM/PM, so I have to call the method lower.

SpecBAS - 64 bytes

PRINT "It's ";LOW$(REPLACE$(TIME$(TIME,"h:mm p$"),"M",".M."))

The built-in p$ of the time function returns AM or PM, so this then has to be formatted with REPLACE$ to change it so it has a full stop before/after that letter.

Then the time output had to be converted to lowercase.

Python 3, 117 87 79 bytes

from datetime import*
print(datetime.now().strftime("It's %I:%M%P")[:-1]+".m.")

This gets the hours and minutes from a 12-hour clock using the format %I:%M, plus am or pm using %P. We then select everything but the last m and append .m..

Saved a few bytes thanks to Ruth Franklin!
