G'day amitvalia,

Time::Piece was added in Perl v5.10 (see perl5100delta: New modules) which is why it wasn't available in your v5.8.6.

I see the documentation has information relating to Win32 and 32-bit Perl: both in the CAVEATS section.

When you unpack Time-Piece-1.33.tar.gz, I'd expect there to be files like README and INSTALL which explain how to do the installation. I've never used Windows Server 2019 so I can't provide any direct help; perhaps another monk has experience in this area. I will note that any commands using make typically need something else for Win32 (e.g. dmake) but I don't have specific knowledge to aid you.
