Another idea. Bear in mind that because your match includes HH:MM your file needs to be totally up-to-date to get a match. I've assumed that the original log file entries came from the "date" command with no parameters.

Code:
today="`date|cut -c1-16`"
grep "${today}" abc161.txt 2>&1 >/dev/null ; reply=$?
if [ $reply -eq 0 ]
then
        echo "File contains: ${today}"
fi
