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

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.

Answer 5

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.

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"

It's 3:09p.m.

Answer 11

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 12

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).

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,'.'))+'.'

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

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.

Excel VBA, 33 bytes

?"It's "format(now,"h:ma/p")".m."

Related to toothbrush's VBA6 solution, but written before I saw it, so I'm allowing myself to post it here.

Most of the code is perfectly explicit: now returns a system timestamp, format forces the timestamp to the desired format, whilst It's and .m. are just text strings.

I abused/took advantage of a few things here:

• Implicit concatenation : VBA assumes that when something is put next to a string that a concatenation operation is desired.

• Immediate window printing : This is why I don't claim this is a complete VBA solution, as it relies on being executed from inside an immediate window. The ? replaces debug.print for Excel VBA in an immediate window. This is an obvious gain for VBA where most of the byte cost comes from descriptive/user-friendly function and method names. Toothbrush's solution for example calls Msgbox which is 5 bytes more expensive.

• Format abuse : based on Dopapp's comments in this puzzle, we don't need to have double-digit hours. I'm also not forcing double-digit minutes, which might be slightly against the rules of the game, but can easily be corrected by adding an extra m between : and m, but costs 1 byte more.

I might have missed some other tricks, but I think this is about as low as Excel VBA can go. From what I can see so far, I'm pretty surprised that it's scoring so well, but a lot of the very concise languages haven't been used yet...

Answer 43

TI-BASIC, 58 bytes

getTimeStr(12
"It's "+sub(Ans,1,length(Ans)-2)+sub("ap",2-not(inString(Ans,"P")),1)+".m.

An ugly hack to build the correct output from the built-in getTimeStr(, which gives something like "8:59 PM". (By the way, the 12 means "12-hour format".)

Answer 44

JavaScript (ES6), 95 bytes

x=(new Date+"").substr(16,5).split(':')
alert(`It's ${x[0]%12||12}:`+x[1]+(x[0]<12?'a':'p')+'.m.')

Answer 45

Hassium, 125 Bytes

func main(){print("It's "+date().hour%12+":"+date().minute);if(date().hour%12!=date().hour)print("p.m.");else print("a.m.");}

Answer 46

Octave 54 bytes

5 bytes shorter than the shortest MATLAB submission and 21 bytes shorter than the shortest Octave submission. Uses Octave's "index everywhere" functionality.

disp(['It''s ',lower(datestr(now,16))([1:5,7]),'.m.'])
It's 12:34p.m.
