PowerShell doesn't cure insomnia

Had a bit of trouble sleeping last night, when I noticed that there was a perceptible difference in the amount of light the digital clock emanates.

It got me wondering what time displays the most light. Sure I could have manually figured it out, but isn't more exciting to write a script?

Here it is:

<#   Define a lookup table for the amount of light "bars" each number displays. #>           

$hash = @{"1"=2;"2"=5;"3"=5;"4"=4;     
   "5"=5;"6"=6;"7"=3;"8"=7;     
   "9"=5;"0"=6;":"=0}     
$max=0     
for ($hour = 1; $hour -le 12; $hour++) {     
for ($minute = 0;$minute -lt 60; $minute++) {     
 $time = "{0}:{1:0#}" -f $hour, $minute     
 $timeArray = $time.ToCharArray()     
 $sum=0     
 foreach ($char in $timeArray) {     
     $sum+= $hash[[string]$char]     
 }     
 if ($sum -gt $max) {     
     $max, $maxTime =$sum, $time     
 }     
}     
}     
"{0}`t{1}"-f $max, $maxTime

Enjoy!
