Here's an ugly one i just whipped together

Code:

$time = @time
$mins = split($time,':')[1]
$minsplusten = (10 + split($time,':')[1]) mod 60
$hours = split($time,':')[0]
if $minsplusten < $mins
   $hours = (1 + $hours) mod 24
   if $hours < 10
      $hours = '0' + $hours
   endif
   $minsplusten  = '0' + $minsplusten 
endif
$CurTimePlusTenMins= "" + $hours + ':' + $minsplusten + ':' + split($time,':')[2]
"CurTime:       " $time ? 
"plus the mins: " $CurTimePlusTenMins
