<p>APRS Spec 1.01: 29 AUG 2000, bottom of page 65 (curse the editor
that didn't put Table #s), "Complete Weather Format -- With
Lat/Long position, No Timestamp" indicates that it should be
valid. HOWEVER, on the previous page, under the "Positionless
Weather Data" heading, you'll see:<br>
"NOTE: The weather report must include at least the MDHM
date/timestamp, wind direction, wind speed, gust and
temperature..."</p>
<p>Ambiguity aside (I think a "Positionless Weather Report" requires
the timestamp), it is valid to have a weather report without
timestamp. Just assume time=now().</p>

<div>The second object parses correctly. The first one does not.</div>

</div>
<div>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?</div>
