</p><p>For date and time values, we use the standard Day and UTCTime types.
</p><p>A <code><a href="Hledger-Data-Types.html#t:SmartDate">SmartDate</a></code> is a date which may be partially-specified or relative.
Eg 2008/12/31, but also 2008/12, 12/31, tomorrow, last week, next year.
We represent these as a triple of strings like ("2008","12",""),
("","","tomorrow"), ("","last","week").
</p><p>A <code><a href="Hledger-Data-Types.html#t:DateSpan">DateSpan</a></code> is the span of time between two specific calendar dates, or
an open-ended span where one or both dates are unspecified. (A date span
with both ends unspecified matches all dates.)
</p><p>An <code><a href="Hledger-Data-Types.html#t:Interval">Interval</a></code> is ledger's "reporting interval" - weekly, monthly,
quarterly, etc.
