[Zope] Inconsistent behaviour in DateTime comparisons

I've got a PostgreSQL DB with date fields, and am using ZpsycopgDa (1.0.13) to connect Zope to it. What I am needing to do is to compare "now" with a date filed stored in the DB. I can get it out just fine, but the comparison is not consistent. I'm doing it in a a Script (Python). (m is smartbrains-enhanced ZSQL result) if DateTime().lessThan( m.expiresdate ): add m to a list else: pass return a list Sometimes it returns correctly, others it returns the opposite of what I want. Simply reloading the page has shown the switch happen -no change to the script. Any help appreciated. Bill -- Bill Anderson <bill@libc.org> Linux in Boise Club
