I have the following logic in my bash script:

#!/bin/bash
local_time=$(date +%H%M)

if (( ( local_time > 1430  && local_time < 2230 ) || ( local_time > 0300 && local_time < 0430 ) )); then
 # do something
fi

Every now and then, I get the error specified in the title (any time above 08xx appears to trigger the error).

Any suggestions on how to fix this?

I am running on Ubuntu 10.04 LTS

[Edit]

I modified the script as suggested by SiegeX, and now, I am getting the error: [: 10#0910: integer expression expected.

Any help?
