Matthew Flatt e85c17b090 add date*' and exn:fail:syntax:unbound' ... The `date*' structure type is an extension of `date' with `nanosecond' and `time-zone-name' fields. The `seconds->date' function now accepts a real and returns a `date*'. The fractional part of its argument goes into the `nanosecond' field. original commit: ac8990d5195312fa7c71966bdfaa925905902ca8		2011-09-29 09:22:10 -06:00
