Simillar to issue #43. The OBJECT bit in the SEXP sxpinfo header is not being set when the value field is a vector with attributes, in this case, POSIXct. The effect is that print.default get dispatched on the vector rather than the appropriate S3 method.

This should be fixed with 0658e7c. Please try the latest development version of reshape2 and confirm the fix works for you as well.

Thanks!

Note that we only use SET_OBJECT as S4 vectors within data.frames is something that we (nor R, AFAIK) don't really support.
