format optional default (empty - defaults to U)A PHP date() format string, such as Y for the year, j.n.Y for day.month.year, or DATE_ATOM for a constant name (any DATE_ constant is resolved). If left empty the format defaults to U, the Unix timestamp.
timestamp optional default (empty - current server time)The moment to format. May be a Unix timestamp integer, or a textual date such as 2008-07-01 that strtotime can parse. A field-getter (for example a publish date) can be combined with math to compute a relative date. If omitted, the current server time is used.
