Adding to archive record after archive record is received?

[Pat]

I'm using MQTT to keep a development system online and receiving data. My source and destination machines have the same archive_interval.

In the MQTT archive packet there's 3 fields I want to extract and put into the development system's archive. 

Since both systems have the same archive interval, the MQTT archive packet comes in a few milliseconds after the development machine has already processed it's own archive interval, so I'm not able to inject the missing observations that I want.

I tried using the archive_delay option in StdArchive set to 20 seconds, but that didn't work - archive ran at the normal 15 second delay time.

Is there a way to delay or to inject the MQTT data into the archive that just closed?

Thanks

Ignore me, archive_delay is working so long as I edit the correct weewx.conf file. :-)
