Fix getting UTC time from formatted strings ( in uw_Basis_readUtc ). Corrects 2 things: - timezones with offsets not an integer number of hours - double correcting for daylight savings time

datatype foo = A | B of bar
and bar = C | D of foo

val q = B (D A)

fun main () = return <xml>
  {case q of
       B (D A) => <xml>Good</xml>
     | _ => <xml>Bad</xml>}
</xml>
