The idea was originally based on the LOCAL-TIME concept proposed by Erik Naggum (1965-2009) in "The Long, Painful History of Time" in 1999.

The implementation was also inspired by the Local-Time package by onShore, Inc. available from http://alpha.onshore-devel.com/lisp-software/ (seems not available any longer).

But Erik had criticized their open source implementation heavily. For example, bignum-based operations were defeating the original efficiency purpose of the LOCAL-TIME.

Taking the critique into account and after realizing drawbacks, the fundamentals were redesigned in Ystok-Local-Time and code was rewritten considerably.

Date/time is represented by one of the following three structures:
