java.text.SimpleDateFormat isn't thread safe (mentioned in the javadoc). You should either:

create a new instance for each use
synchronize the use
or use another formatter (e.g. FastDateFormat from commons-lang, but note that it cannot parse)

I forgot about this issue, SimpleDateFormat is backed by a Calendar instance. :-(

Right now, I'm thinking I'll move to Joda time.

I removed calls to the standard Java date functions and replaced them with calls to Joda time.
