Ok, time for some fancy stuff (it's friday after all ;)):

ecasound -i /dev/dsp -o somefile.ogg -ea:100 -kl2:1,0,100,XXX,3 -ge:1,0 -t:YYY

Start recording after XXX seconds has passed, with 3sec fade-in. Then
record for YYY-XXX seconds. Or without the fade-in:

ecasound -i /dev/dsp -o somefile.ogg -gc:XXX,YYY -t:ZZZ

Start recording after XXX seconds, and then record for YYY secs. ZZZ
should be value greater than XXX+YYY (just to make sure ecasound exits at
some point).

I'll leave the 'time-shifted recording with both fade-in and fade-out' as
an exercise. :) And yup, not necessarily very convenient. You should
still take a look at cron and at.

Btw; The same thing applies here for reliability, so add
     "-z:intbuf -z:db -r" to the options.
