What's the time, chap?

Question

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!

Answer 1

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.

A solution that uses essentially the same method in Ruby, which is surprisingly the exact same length:

Ruby, 39 bytes

$><<`date "+It's %I:%M%P"`[0..-3]+'.m.'

Answer 2

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.

Answer 3

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.

Visual Basic 6 / VBA, 42 41 bytes

MsgBox"It's "&Format(Now,"h:mma/p")&".m."

Using MsgBox, as VB6 does not have a console (unless you intercept the linking, link as a console executable, use some Windows API hacks, and do some other dodgy stuff).

Answer 5

R, 68 ,59 62 60 55

cat("It's",sub("m",".m",format(Sys.time(),"%I:%M%P.")))

(Thanks to @Alex.A. and @flodel for the comments) Takes the current system time (Sys.time()), formats it correctly using %I:%M%P combination, adds a dot at the end, and replaces the m with .m..

Answer 6

Julia, 74 54 43 bytes

print(strftime("It's %I:%M%P\b.m.",time()))

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.

MATLAB, 59 bytes

disp(sprintf('It''s%s\b.m.',lower(datestr(now,'HH:MMam'))))

It's 5:38p.m.

If it's allowed to have a whitespace between time and a.m./p.m., then it could be as low as 52 bytes:

disp(sprintf('It''s%s\b.m.',lower(datestr(now,16))))

It's 5:39 p.m.

Answer 10

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).

Answer 11

Perl 5, 74 bytes

A small showcase of how the variables are evaluated from right to left.

($s,$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
It's 3:09p.m.

Answer 12

CJam, 40 bytes

"It's "et3=CmdCe|\'p'a?':et4=s2Ue[@".m."

Try it online in the CJam interpreter.

How it works

"It's " e# Push that string.
et3=    e# Select the fourth element of the date/time array (hours).
Cmd     e# Push quotient and remainder of the hour divided by 12.
Ce|     e# Logical OR with 12 to map 0 to 12.
\'p'a?  e# Select 'p' if the quotient is 1 and 'a' if it is 0.
':      e# Push that character.
et4=    e# Select the fifth element of the date/time array (minutes).
s2Ue[   e# Cast to string and left-pad with zeroes to a length of 2.
@".m."  e# Rotate 'a' or 'p' on top of the stack and push ".m.".

T-SQL (2012+), 67 65 bytes

SQL Server 2012 finally gave us a reasonable formatting function for dates. I still had to muck around with the AM/PM to get the format right though.

PRINT 'It''s '+LOWER(STUFF(FORMAT(GETDATE(),'hh:mmtt.'),7,0,'.'))

In previous versions it would have needed something like this (93 bytes)

PRINT'It''s'+LOWER(STUFF(STUFF(RIGHT(CONVERT(VARCHAR,GETDATE(),109),15),6,7,''),8,0,'.'))+'.'

If only it were am/pm instead of a.m./p.m....

SQL (PostgreSQL), 42 41 bytes

Another SQL variant, however this one is in a query.

select to_char(now(),'"It''s" HH:MIa.m.')

As a note either p.m. or a.m. works to get the am/pm part. The formatting options in PostgreSQL are really quite flexible. Thanks to @manatwork for the tip to move the it's into the format string.

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

Locale-dependent

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

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.")

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

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.

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.

Answer 26

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.
