Unix AWK doesn't have strptime function, which makes life a little messy.
An example to calculate the Epoch time is as fallows but it is a little ugly too.
works for me as a quick way to get things done.
cat /var/log/yum.log | awk 'BEGIN { mnts="JANFEBMARAPRJUNJULAUGSEPOCTNOVDEC"; ST=mktime("2015 11 18 11 32 00"); EN=mktime("2015 12 18 11 33 00");}{ MON=$1; DAY=$2 ; split($3,TM,":"); M=((index(mnts,toupper(MON)))+2)/3+1; EPOCH=mktime("2015 "M" "DAY" "TM[1]" "TM[2]" "TM[3]); if ((ST < EPOCH)&&(EN > EPOCH)) { print $0; }}'
