Problem in understanding the output of errpt -d H -T PERM -s `date +"%m%d%H00%y"`

Its very critical and 'm in need to schedule this on my crontab so that the output can be monitored by a tool
I have written the command below to redirect the error which has the output redirected to the file gincle_lol.log.

Code:
echo "---" >>/gingle/gincle_lol.log
date >>/gingle/gincle_lol.log
errpt -d H -T PERM -s `date +"%m%d%H00%y"` >>/gingle/gincle_lol.log
echo "--" >>/gingle/gincle_lol.log
I want to know what will be the output, because i have written this command to redirect the output which has hardware Permanent errors from the current time -1
Output
This will give you the output of the errors happened current time -1
Eg: If the job is run @ 6:00 then -1 the output will contain the errors between 5 and 6

Code:
7=> 6-7
8=> 7-8
9=> 8-9
10=>9-10
Note: The job is scheduled every 1 hour

Current me if �m wrong�
Please help me on this front... Its critical.
