awk - change variable on fly

Hello All,

I have csv file, where one of fields is date (yyyy/mm/dd 00:00:00). Using awk I am trying to find all records with date newer/older than specific date. My idea was to compare unix timestamps of both dates:
Code:
start=`date +%s -d "$DateStart"`
awk -v start="$start" -v current=`date +%s -d $10` 'current < start' file.csv > temp.file

However awk dont "see" variable $10. Is there any way to pass value from this field to date command?

Thank you in advance for any tips.

Kind regards,
