Strange output log of crontab


Hey, guys:
I was trying hard to set up crontab to get mails every 1 minute. My crontab file looks like this

Code:
 */1 * * * * /usr/bin/fetchmail -aK -m "/usr/bin/procmail -d %T "
Then I activated cron logging. Here is what I found appearing in the log file (i.e. /var/log/cron.log)

Code:
 May 29 22:33:01 Thinkpad-T61 /USR/SBIN/CRON[4390]: (kuangchen) CMD (/usr/bin/fetchmail -aK -m "/usr/bin/procmail -d )
My question is
* What does the %T mean in
Code:
/usr/bin/fetchmail -aK -m "/usr/bin/procmail -d %T "
* Why does it appear that the command is truncated, i.e, missing from %T?

In 'man fetchmail' at "-m " it says it's the local address procmail is told by fetchmail to deliver e-mail to. Next time maybe research before running something?

In 'man 5 crontab' it reads "Percent-signs (%) in the command, unless escaped with backslash (\), will be changed into newline characters, and all data after the first % will be sent to the command as standard input."
