Description Liam R E Quin 2014-12-04 03:30:21 UTC 
The grammar for parse-ietf-date has

S ::= 	x09 | x0A | x0D | x20

but the prose (in a Note) says, the function... Accepts one or more whitespace characters (x20, x09, x0A, x0D) wherever a single space is required, and allows whitespace to be omitted where it is not required for parsing

Probably it would be clearer to use

S ::= 	( x09 | x0A | x0D | x20 )+
