Modelling Periodic Temporal Notions by Labelled Partitionings
of the Real Numbers - The PartLib Library.
Abstract
The key notion for modelling calendar systems and many other
periodic temporal notion is the mathematical concept of a partitioning of
the real numbers. A partitioning of R splits the time axis into a sequence
of intervals. Basic time units like seconds, minutes, hours, days, weeks,
months, years etc. can all be represented by partitionings of R with nite
partitions. Besides the basic time units in calendar systems, there are a
lot of other temporal notions which can be modelled as partitions: the
seasons, the ecclesiastical calendars, nancial years, semesters at
universities, the sequence of sunrises and sunsets, the sequence of the
tides, the sequence of school holidays etc. In this chapter a
formalisation of periodic temporal notions by means of labelled
partitionings of R is presented. The formalism is implemented as the C++
library PartLib (Partitioning Library). The interface to PartLib is
presented in the appendix.
