I do not have GNU date. So I got frustrated with limited options to get elapsed time in Unix,, I wrote a method in Java and using it..
If this works I could replace java method with this..

Code:
diffTime=`expr ${endTime} - ${startTime}`

Does this approach work if a main program is calling say 1. common functions included from other ksh programs and 2. included java programs(from jar/class) ? I know PID is same thrughout the execution of my program.

In other words can we use this to reliably find elapsed time to execute complex Admin scripts in Unix ?

say my environment variable is this
Quote:
SECONDS=1111
: once I execute abc.sh Does it start incrementing SECONDS as soon as any PID starts in the runtime and ends incrimenting before that PID exits from shell !?
