If you're going to write a new APRS client, you need to get a copy
of aprs101.pdf and read it, study it, read it, and study it some
more. Most of your basic questions will be answered therein, like
the fact that messages have NO timestamp! Also, on page 22 (32 in
acrobat) it says:<br>
<br>
<blockquote type="cite">Hours/Minutes/Seconds (HMS) format is a
fixed 7-character field,<br>
consisting of a 6-digit time in hours, minutes and seconds,
followed by the h<br>
time-indicator character. For example:<br>
<br>
234517h is 23 hours 45 minutes and 17 seconds zulu.<br>
<br>
Note: This format may not be used in Status Reports.</blockquote>
<br>
Note the ZULU mentioned on the next to last line.<br>

Does APRS-IS send out 'h' timestamps as local, UTC, or as
received from source?<br>
<br>
If I am doing a HUD display for messages (or other stuff in
the future) do I care about the timestamp? <br>
