Ohhh, I was really hoping on that one...but no, it still reports 0
seconds.
Maybe there's something in the script itself that's messing this up.
Here is the entire script:
#!/usr/local/bin/bash
# Daily Report
# Declare variables
start_time=`date +%s`
time1=`date +%R`
month=`date +%b`
day=`date +%e`
# Cleanup files
if [ -a /root/daily.log ] ; then
rm /root/daily.log
fi
# Main report header
echo "Daily Report for Larry for" `date '+%A, %B %d %Y'`"." >>
/root/daily.log
