from the documentation:

http://www.freebase.com/view/guid/9202a8c04000641f800000000544e143#id2610086

it says dates without timezone, like in my query "2008-06-23T16:12:55":

 "If no timezone is specified, then then the /type/datetime value is assumed
  to be a local time in an unknown timezone."

its confusing because when you say "local time" it implies the local
timezone, yet it says an unknown timezone.  i thought my query's time
would default to the local timezone (-700 for me), but then the first
result above wouldn't pass the time constraint:

 "2008-06-23T21:04:43.0001Z" >= "2008-06-23T16:12:55"

but if it was interpreting "2008-06-23T16:12:55"'s timezone as UTC, then
it would make sense.

basically, does "2008-06-23T16:12:55" default the timezone to UTC?

thanks,
augusto.
