Converts a string containing an ISO 8601 encoded date and time to a TimeVal and puts it
into time_.
iso_date must include year, month, day, hours, minutes, and seconds. It can optionally include fractions of a second and a
time zone indicator. (In the absence of any time zone indication, the timestamp is assumed to be in local time.)
