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

table t : {A : int}

fun main () : transaction page =
    () <- dml (INSERT INTO t (A) VALUES (0));
    return (error <xml>No way, Jose!</xml>)
