[aprssig] APRS Object & Weather format

I've been going over the APRS 101 specification and teasing it apart using
Heikki's excellent Ham::APRS::FAP library.

Page 66 of the APRS101 document gives two example weather report formats as
# Complete Weather Report Format — with Object and Lat/Long position
;BRENDA   *4903.50N/07201.75W_220/004g005t077r000p000P000h50b09900wRSW
;BRENDA   *092345z4903.50N/07201.75W_220/004g005b0990

The second object parses correctly. The first one does not.

>From what I can figure out, the reason is because the first object doesn't
have a valid time stamp. The 101 spec seems to indicate that Objects
require a time stamp. So, is the first object truly invalid, or is a
weather object without a timestamp a valid exception?
