%date gives incorrect dates.

[kupietools]

I use the following custom command to send my alerts to terminalnotifier, so that I can log the parameters for troubleshooting purposes:

/bin/bash /Users/home/Dropbox/Documents/IT/Shell\ Scripts/terminalNotifierForThunderbird.sh -s %sender -d %date -t %time -j %subject -f %folder -u %msg_uri

My log entries show that, for instance, for an email dated 10/21/15 10:28 PM, Mailbox-alert sends the value 6/20/47775 as %date and 2:03:20 AM as %time.

This is a problem because I am migrating over 65,000 old emails from another account, and I don't want to turn off alerts because then I couldn't see new emails come in, but I want to filter by date in my script to prevent me from getting 65,000 alerts. I can't figure out how it's getting the values it's sending as dates, though.
