Answer 1

Use a timestamp, bash can't compare dates.
Use declare -i, otherwise all bash variables default to a string, not a number.
the --date option allows you to specify which date you want to use
date --date="2011/12/12 12:12:12"
Monday, 12 december 2011 12:12:12 +0200
+%s option allows you to display the desired date using date date as "seconds since 1970", get integers that bash can compare. Simple example:

#!/bin/bash

declare -i MYDATE1=`date --date="2011/12/12 12:12:12" +%s`
declare -i MYDATE2=`date --date="2017/07/06 11:11:11" +%s`
declare -i CURRDATE=`date +%s`

echo $MYDATE1 $MYDATE2 $CURRDATE

if [ $MYDATE1 -lt $CURRDATE -a $MYDATE2 -gt $CURRDATE ]; then
  echo "Сейчас больше чем $MYDATE1 и меньше чем $MYDATE2"
else
  echo "не-а"
fi

The command dateis able to issue the date in the required format, it is not necessary to pervert with cat and awk: date +%H:%M:%S. Bash does not know how to compare dates, you can convert them to Unix epoch and compare them as numbers.
