Es ist schon [aktuelles Jahr], Leute, geht nach Hause

Auf den meisten Herausforderungen , wenn es zur Zeit nicht das entsprechende Jahr der Herausforderung ist, es sagt , das in der Front.

Es ist schon [aktuelles Jahr], Leute, geht nach Hause.

Sie müssen diesen Text mit dem ersetzten aktuellen Jahr ausgeben.


I / O

Eingabe: Keine.

Ausgabe : It's [year] already, folks, go home.mit [Jahr] auf das aktuelle Jahr geändert.

Kann ich Eingaben nehmen und sie dann ignorieren (dh etwas in der Art von tun String goHome(Object foo){return "It's "+currentYear()+" already, folks, go home.";}(aber natürlich viel kürzer))?

@RobertFraser To run any C (gcc) answer on this site you run it as gcc golf.c && ./a.out. That in this process a binary is formed is irrelevant for code golf. My source code is being judged, not the binary being generated (if that was the case my answer would be x86-64).

Nitpickers ... @orlp, since __DATE__[6] is a space, you can spare one byte: ..."It's%s already, folks, go home.",__DATE__+6);} (mind the missing space between It's and %s).

Bash, 45 characters

printf "It's %(%Y)T already, folks, go home."

Bash's built-in printf in version 4.2 got the %(fmt)T format specifier and since version 4.3 it defaults to current timestamp in absence of argument.

Sample run:

bash-4.3$ printf "It's %(%Y)T already, folks, go home."
It's 2017 already, folks, go home.

Even though the input from the BIOS is in BCD (as opposed to the plain 16 bit value got from the equivalent DOS call), decoding it to ASCII turned out to be almost as long as base-10 printing a register. Oh well.

TI-Basic (TI-84 Plus CE with OS 5.2+), 64 bytes

getDate
"It's "+toString(Ans(1))+" already, folks, go home.

TI-Basic is a tokenized language. Some commands (getDate, toString(, etc.), and all lowercase letters are two-bytes and everything else used here is one byte each.

Explanation:

getDate                                             # 3, store {Y,M,D} in Ans
"It's "+toString(Ans(1))+" already, folks, go home. # 61, implicitly return required string with Y from getDate

TI-Basic (TI-84 Plus CE with OS 5.1), 108 bytes

{0,1→L1
getDate
Ans(1)L1→L2
LinReg(ax+b) Y1
Equ►String(Y1,Str0
sub(Str0,1,length(Str0)-3→Str0
"It's "+Str0+" already, folks, go home.

TI-Basic is a tokenized language. The more complicated user variables (Y1, L1, L2, Str0), some commands (LinReg(ax+b , getDate, sub(, Equ►String(, length(), and all lowercase letters are two-bytes and everything else used here is one byte each.

OS 5.2 added a toString( command, which obsolesces about half of this submission, which is based off of this algorithm.

Explanation:

{0,1→L1                                  # 8 bytes
getDate                                  # 3 bytes, store {Y,M,D} list in Ans
Ans(1)L1→L2                              # 10 bytes, multiply L1 by the year and store in L2
LinReg(ax+b) Y1                          # 5 bytes, take a linear regression of the points specified by each pair of corresponding coordinates in L1 and L2 and store it in Y1
Equ►String(Y1,Str0                       # 8 bytes, convert Y1 to a string
sub(Str0,1,length(Str0)-3→Str0           # 18 bytes, remove the "X+0" from LinReg
"It's "+Str0+" already, folks, go home.  # 56 bytes, implicitly return the required output

you can inline L_1 in the 5.1 programs. gets rid of a newline, two "L_1" tokens, and a →. 6 bytes saved?
striking
@striking LinReg(ax+b) uses L_1 and L_2, so I have to set them both.

Save some bytes on the first: use max(getDate) instead because the largest number in getDate is always the year.

Haskell, 113 bytes

import Data.Time.Clock
f=do t<-getCurrentTime;putStr$"It's "++(fst.span(>'-').show)t++" already, folks, go home."

Try it online! Replace f with main for a full program.

The function getCurrentTime returns a UTCTime object which looks something like "2017-04-02 10:22:29.8550527 UTC" when converted to a string by show. fst.span(>'-') takes the leading characters while they are larger than '-', that is the current year. For the next 7972 years take 4 would work for 8 bytes less, but we want our code to work correctly for ever and ever.

As far as I see build-in functions to get the current year require a import Data.Time.Calendar, so extracting the year from the string should be the shortest option.

Try it online!

Thanks to James Holderness for pointing out my mistake with the sysinfo instruction.

"emoh og ,sklof ,ydaerla@ s'tI" pushes the sentence to the stack where 4k, prints the first word. y is the sysinfo instruction. When passed 20 (the unprintable in the string), it returns 256*256*(year-1900) + 256*month + day of month. \4*:*/"&2"*+. takes just the year from the value and prints it andf7+k, prints the rest of the sentence.
