timestamps

Hello!

I have the following problem.
I read a file using perl, each line of this file has the fllowing format.
14/4/2008 8:42:03 |10800|306973223399|4917622951117|1||1259|1|126|492|433||19774859454$

Th first field is the timestamp and the second field is the offset in seconds.

How can i add these two fields and produse one timestamp?

str1="14/4/2008 8:42:03 |10800|306973223399|4917622951117|1||1259|1|126|492|433||19774859454$"
echo "$str1"awk 'BEGIN {FS="|"}{print $1}'
