This should be incredibly simple, but can't get it to work.
All I want to do is pause a script between 11:00 am and noon.

I receive the following error:
time.sh[4]: 13:55:45: syntax error

script:
1 while true
2 do
3 TIME=$(date '+%H:%M:%S')
4 if [ $TIME -ge 11:00:00 ] -a [ $TIME -le 12:00:00 ]
5 then
6 echo "time between 11:00 and noon"
7 echo sleep time $TIME
8 sleep 3
9 else
10 echo "time all others"
11 fi
12 done
