// 'selector' = a CSS selector string that selects the nodes containing
// times in the format described by 'format'
// if the time is split across > 1 node (eg. the date in one node and
// the time in another), those nodes must be consecutive in the list of
// nodes matching the selector
// ---------------------------------------------------------------------
// 'format' = a string describing the format of the date/time text in
// the nodes (eg. "m-d-y|h:i:s T")
// the following placeholders are used to indicate where in the text
// that component should appear:
// W : weekday name
// d : 2-digit day number (01-31)
// D : 1 or 2-digit day number (1-31)
// m : short month name
// M : long month name
// n : 2-digit month number (01-12)
// Y : 4-digit year
// y : 2-digit year
// h : 2-digit hour (00-23)
// i : 2-digit minute (00-59)
// s : 2-digit second (00-59)
// T : timezone
// other special characters are:
// space : matches one or more whitespace characters
// | : indicates where the text is split across nodes
