There's of course established ways to do things in GNU/Linux but I'm just used to the "wait until" way... so I tinkered in bash:

#/usr/bin/bash
# wait sort of like "wait until" in AmigaDOS
typeset -i untiltime=`date +%s -d"$1"`
typeset -i rnow=`date +%s`
sleeps=`expr $untiltime - $rnow`
if [[ $rnow > $untiltime ]] then
  echo "No time to wait.";exit
fi
sleep $sleeps
