Question Start Time and period of a PID

Hi,

Below is my OS details.

Code:
uname -an
SunOS mymachine 5.10 Generic_144488-07 sun4v sparc SUNW,SPARC-Enterprise-T5220

I need to know when was my Apache server last started. Whats is the best and most reliable way to find out not just for Apache but for any PID per say?

I am also confused as to what is the best way to find the PID[unique] of the apache server running on my unix box.

Below command returns multiple PIDs which is confusing.

Code:
ps -ef | grep -i "httpd"

wlsuser 15709  8392   0 03:55:18 ?           0:29 /apps/apache22/bin/httpd_worker -DSSL -k start -f /apps/apache22/conf/httpd.con
wlsuser  8459  8392   0   Nov 20 ?           0:00 /apps/apache22/bin/httpd_worker -DSSL -k start -f /apps/apache22/conf/httpd.con
wlsuser  8392  6839   0   Nov 20 ?           5:25 /apps/apache22/bin/httpd_worker -DSSL -k start -f /apps/apache22/conf/httpd.con
wlsuser  7019  8392   0 00:24:51 ?           3:12 /apps/apache22/bin/httpd_worker -DSSL -k start -f /apps/apache22/conf/httpd.con
wlsuser 26856 26159   0 04:19:11 pts/2       0:00 grep -i httpd
wlsuser  3514  8392   0 22:13:07 ?           4:05 /apps/apache22/bin/httpd_worker -DSSL -k start -f /apps/apache22/conf/httpd.con
wlsuser 25218  8392   0 00:03:23 ?           3:11 /apps/apache22/bin/httpd_worker -DSSL -k start -f /apps/apache22/conf/httpd.con
wlsuser 13385  8392   0 23:40:55 ?           3:18 /apps/apache22/bin/httpd_worker -DSSL -k start -f /apps/apache22/conf/httpd.con
