In your first example, you are looking for timestamps that are exactly 10 minutes ago OR now; not the range of timestamps between those two timestamps, inclusive.

Without seeing sample input, it is hard to imagine getting the output you're showing from your second example, but you are missing required spaces in your if statement:
Code:
if [ $2>="$(date -d '45 minutes ago' "+%H:%M:%S")" ]

needs to be changed to:
Code:
if [ $2 >= "$(date -d '45 minutes ago' "+%H:%M:%S")" ]

or, even better:
Code:
if [ "$2" >= "$(date -d '45 minutes ago' "+%H:%M:%S")" ]
