Hi,
would be nice to have a central component to handle that.
I can imagine that the "local time handling" will require more tweaks to
get complete, too.
I will keep the idea in mind for the next change.
BTW: I think the GT have their own internal date representation (for such
"BC" cases). Right?
Best regards,
Andreas
