// the format returned by the date_format() calls below or by retrieval as
// strings, unless $datetimetype is date or time. In that case, if
// $returnStrings is false and $datetimetype is 'date', the time defaults to
// 00:00:00.0000, and if $datetimetype is 'time' and $returnStrings is false,
// the date defaults to the current date. If however $returnStrings is true
// and $datetimetype is 'date', $retrieved_date is only a date,
// and if $datetimetype is 'time' and $returnStrings is true, $retrieved_date

// The concatenations involving zeroes below are to make direct string
// comparisons feasible. Also, because PHP maxes out at microsecond precision
// and SQL Server maxes out at 0.1 microsecond precision, the more precise
// types require an extra 0 for some comparisons.
