Ja, good catch.  What I need then is this:

Larry lies on vowel months and truths on consonant months.  His brother
Darrel is even more dishonest, truthing only on vowel months and lying on
consonant months.

Larry comments:  I lied a month ago.  I will lie again 180 days from now.

Darrel comments:  Larry is lying now.

How can this be?



That version kinda gives away what I had in mind and has multiple correct
answers, but actually is a better puzzle.  It shouldn't be too hard to
figure out all the possibilities with this version.
