Should be fixed now, please test. 

I've also added a time support. The plugin looks for string fields containing 
date and time in one of following formats:

YYYY/MM/DD hh:mm
MM/DD/YYYY hh:mm

where the date separator can be either / - .
and the separator between the date and time can be space or letter T

So following format is also accepted:
05-31-2010T23:40

If the date/time field is found, columns with mean time and time difference 
(in minutes) are added to the output.
