In corrispondance with the author of Date::Tie, a few benchmarks were passed around (by him). The conclusion is that when compared to DateTime, Date::Tie is considerably faster. My suspicions were correct when it was discovered that Time::Piece was considerably faster than Date::Tie.
Even so, way to go Date::Tie for beating DateTime. I fell victim to the default expectation that anything tied is slow. While that holds true, tied interfaces aren't always the slowest, so do your benchmarking.

Funny because Time::Piece 2.00 (not yet out of beta) ISA DateTime.
I'm not sure that performance is that critical - it's probably in the thousands of operations per second region. And DateTime buys you so much - a unified base class with support for decimal second values and dates outside the 1970-2038 region.
Um, but is it correct and/or useful

Does Date::Tie handle leap seconds? Does it do _anything_ at all useful with time zones? How flexible is its date math? Does it handle dates outside the epoch?
There are a number of things DateTime does that literally no other Perl date/time module can do. If you need any of them, then you probably are stuck with DateTime
;)
Note that the author of Date::Tie is also a major contributor the DateTime project as well.
