MongoDB stores dates as milliseconds past the epoch. This means that dates
<em class="emphasis">do not</em> contain timezone information. Timezones must be
stored in a separate field if needed. Second, this means that any precision
beyond milliseconds will be lost when the document is sent to/from the
database.
