Ah, I hadn't noticed the whitespace before. The grammar in RFC 2254 doesn't
appear to permit additional whitespace in the expression, so you should
probably try to avoid adding it where you don't need it.

Possibly the whitespace in front of the values you're testing ("
20020812000000.0Z") are being considered as part of the value to be
compared against, which is also causing problems.

Anyway, I suspect removing unnecessary whitespace from your filter string
will solve at least some of your problems.

Cheers,

Chris
