Date added for basket items

[Aaron]

Is there a way to make the date added in the customers basket more granular?  Right now it only shows the year/month/day, but we'd like to be able to see the hour/minute as well.  Is there a reason this field is a CHAR field and not a DATE field?

The reason behind this is that we'd like to be able to do some re-marketing based on how long an item has sat in a customers basket without being purchased, and we'd like to be able to do increments smaller than just the previous day.

Thanks,
Aaron
