- vector->xml-rpc-iso8601 time-vectorprocedure
This procedure encodes a "time vector" (10-element vector, as returned by eg seconds->local-time) to an iso8601 string representing the same date. Currently this procedure is not in the parameter list by default, because it's impossible to differentiate between a regular vector that just happens to be 10 elements long and a "time-vector". The same problem exists for integers and the "seconds since the epoch" representation of time.
Using srfi-19 is a solution to this problem, as it provides a distinct datatype for date/time objects. But you would have to make your own conversion routines in this case.
