由于我为《Final Fantasy XV Uncovered》事件大肆宣传，因此我希望您编写一个程序告诉我何时发生！

输入

您的汇整输入形式为HH:MM XDT，其中HH是范围内的数字1-12，MM是之间的数字0-60，并且XDT是时区，并且X是E（东部，UTC-4），C（中央，UTC-5），P（太平洋， UTC-7）或M（山，UTC-6）。这是假定为下午的时间。有效输入包括：

1:00 EDT (1 PM Eastern Daylight Time)
4:05 MDT (4:05 PM Mountain Daylight Time)
12:23 PDT (12:23 PM Pacific Daylight Time)
1:10 CDT (1:10 PM Central Daylight Time)

该输入可以被认为是有效的。

输出

您的程序必须执行以下操作：

1. 将给定时间转换为PDT并输出It is XX:XX PM PDT.，其中XX:XX是转换后的时间。请注意，你不会需要处理，其中转换的时间将跨越AM / PM边界的任何情况。

2. 打印以下内容之一：

   1. 如果转换后的时间是前下午六时PDT，打印X minutes until the pre-show!，替换X与到下午6点的PDT的分钟数。

   2. 如果转换后的时间在PDT下午6:00之前和PDT 7:00之前之后，请打印Pre-show started X minutes ago; UNCOVERED is starting in Y minutes!，其中PDTX是自6:00 PM PDT经过Y的分钟数，是7:00之前的分钟数。太平洋夏令时间。

   3. 如果转换的时间在PDT 7:00 PM之后或等于7:00 PM PDT，则打印UNCOVERED started X minutes ago!，这里X是PDT 7:00 PM之后经过的分钟数。

每个打印的字符串必须后跟换行符。

计分

这是代码高尔夫，所以最短的程序会获胜。

JavaScript（ES6），257个字节

s=>(t=` minutes`,a=s.match(/(\d+):(\d+) (.)/),h=+a[1]+"PMCE".search(a[3]),m=420-h*60-a[2],`It is ${h}:${a[2]} PM PDT
${h<6?m-60+t+` until the pre-show`:h<7?`Pre-show started ${60-m+t} ago; UNCOVERED is starting in ${m+t}`:`UNCOVERED started ${-m+t} ago`}!`)

Python（335字节）

t=raw_input().replace(*': ').split();x='PMCE'.index(t[2][0]);t[0]=int(t[0])+x;print '%s:%s PM PDT' % tuple(t[:1]);x=t[0]*60+int(t[1]);print ['%s minutes until the pre-show!'%(360-x),'Pre-show started %s minutes ago; UNCOVERED is starting in %s minutes!'%((x-360),(420-x)), 'UNCOVERED started %s minutes ago!'%(x-420)][(x>360)+(x>420)]

输出：

1:00 MDT
2:00 PM PDT
240 minutes until the pre-show!

6:00 CDT  
8:00 PM PDT
UNCOVERED started 60 minutes ago!

6:50 PDT
6:50 PM PDT
Pre-show started 50 minutes ago; UNCOVERED is starting in 10 minutes!

Lua中，357个 335 332字节

感谢@Katenkyo砍掉22个字节。

打高尔夫球：

h,m,t=(...):match("(%d+):(%d+) (.)")f=tonumber h=(f(h)-("PMCE"):find(t))%12+1m=f(m)print("It is "..h..":"..m.." PM PDT.")a=" minutes"b="UNCOVERED"n=(6-h)*60-m r=h<6 and n..a.." until the pre-show!"or h<7 and"Pre-show started "..m..a.." ago; "..b.." is starting in "..(n+60)..a.."!"or b.." started "..(m+(h-7)*60)..a.." ago!"print(r)

（在线尝试）

取消高尔夫：

n = "7:10 CST"

h,m,t = n:match("(%d+):(%d+) (.)")
h = (tonumber(h) - ("PMCE"):find(t))%12 + 1
m = tonumber(m)
print("It is "..h..":"..m.." PM PDT.")

n = (6-h)*60-m

if h<6 then
  r=n.." minutes until the pre-show!"
elseif h<7 then
  r="Pre-show started "..m.." minutes ago; UNCOVERED is starting in "..(n+60).." minutes!"
else
  r="UNCOVERED started "..(m+(h-7)*60).." minutes ago!"
end

print(r)

C，333字节

#define p printf
char s[9];main(t){gets(s);s[5]=0;s[1]-=2+s[6]%2-s[6]%3;s[1]<48&&(s[1]+=10,--*s);
t=*s*600+s[1]*60+s[3]*10+s[4]-32568;p("It is %s PM PDT.",s);
t<0?p("%d minutes until the pre-show!",-t):t<60?p(
"Pre-show started %d minutes ago; UNCOVERED is starting in %d minutes!",t,60-t):
p("UNCOVERED started %d minutes ago!",t-60);}

删除不必要的换行符（除#define之后的所有换行符）后的333个字节。

PHP，347个 328 327 322字节

<?=$u="UNCOVERED";$m=" minutes";$s=" started ";$p="re-show";$z=['P'=>0,'M'=>1,'C'=>2,'E'=>3];$i=explode(":",$argv[1]);$h=$i[0]%12-$z[$argv[2][0]];$o=$i[1];$t=60-$o;$a="$s$o$m ago";echo"It is ".(($h+11)%12+1).":$o".($h<0?"

分解图

<?=
  $u = "UNCOVERED";
  $m = " minutes";
  $s = " started ";
  $p = "re-show";
  $z = [ 'P' => 0,
         'M' => 1,
         'C' => 2,
         'E' => 3 ];

  $i = explode(":", $argv[1]);
  $h = $i[0]%12 - $z[$argv[2][0]];
  $o = $i[1];
  $t = 60 - $o;
  $a = "$s$o$m ago";

  echo "It is " . (($h+11)%12+1) . ":$o" . ($h < 0 ? " A" : " P") . "M PDT.\n" .
       ($h < 6 ? $t . "$m until the p$p!"
               : ($h < 7 ? "P$p$a; $u is starting in $t$m!"
                         : "$u$a!"));
?>

运行为php script.php HH:MM XDT。将时间和时区作为$argv条目，从正则表达式中$argv[1]取出$i = [HH, MM]，从第一个字符开始确定时区$argv[2]，算出6PM PDT之后的分钟数，然后三进制echo。

可以使用丢弃2个字节$u=UNCOVERED，但这是这里唯一的错误，我喜欢它可以正常工作。

PowerShell 292字节

少打高尔夫球的解释

# Several string literals were used to save space.
