How to change the outbound notification attachment window?

Background

JEMH can include attachments in outbound notifications, but they must have been created within a specific time window for the current event.  The default value is 30S.  In most cases this doesn't need changing.

 Available in 1.3.30.3, 1.3.53+, 1.4.21+

Customize the window

JEMH has an environment variable that can be used to tweak this value (its in milli seconds, so 30S is 30*1000 = 30000; 1h is 60*60*1000 = 3600000).  The usual setenv.sh / setenv.bat needs a new variable defining, e.g. to make the window 1hour, add:

 
-Djemh.attach.window=3600000

The exact place could be anywhere, here is an example changed line:
