virex cron

[lists3-200402]

does anyone know how to append a date to a summary for a virex cron 
job? i got things set up on my client servers so the sharepoints are 
scanned nightly, infected files are moved to a quarantined folder, 
and a summary is appended to a text file...but the appended summary 
doesn't include the date. anyone know how this is done? i checked the 
virex 7.2.1 manual and it doesn't seem to have a switch for that. 
here's my command:

/usr/local/vscanx/vscanx --move /SERVER/VOLUME/VIREX_OUT/QUARANTINE 
/SERVER/VOLUME/SHARE --recursive --unzip --atime-preserve 
--ignore-links  --summary >> /SERVER/VOLUME/VIREX_OUT/SUMMARY.TXT

thanks,
don
