It _is_ a bug (in e1071), since svm() is indeed supposed to support

The TODO list of Seth Falcon's weaver

However, since so many packages depend on the basic Sweave implementation by

Looking forward to your opinions and pointers.

Thank you for the report. In R-devel, all.equal.POSIXt() by default
reports inconsistent time zones. Previously,

would return TRUE. To ignore the time zone attributes in R-devel, the
argument 'check.tzone = FALSE' needs to be used.
