That's what all B-flights do as well.  There is no compressed timestamp available in APRS specification so i just dreamt up my own.

There are encoded time and datestamps in each realtime and backlog message sent from B-**.  Without them there is no way to untangle APRS timing mess.  

There are stations sending packets with 30-60 minutes delays and dutifully lists them under delayed times.

...note "W{h)" in front of /A=040836 - this is an encoded GPS date/time stamp.  It decodes to "10th of October, 07:10:41"
