Chapter 2. Glossary

interval (time)

A time interval is the distance or difference between two timepoints on a timescale. If repeated regularly, intervals can be measured in metric units, which are in the context of synkronize: seconds, minutes, hours, days, weeks, months, years.

interval granularity

The 'granularity' of a timescale, i.e. another word for "unit". Units are seconds, minutes, hours, days, weeks, months, years.

interval scale

An interval scale is a metric scale that allows to measure quantity and difference of values in metric units. In regard to time and date, in the context of synkronize, these values are timepoints on a timescale in units like seconds or days.


The term 'onset' is borrowed from music theory where it is used to mark the beginning of a note, but doesn't denote pitch or length. Likewise the onset in regard to timepoint generation for scheduling marks the starting of some action, without specifying the action itself or its duration.


A time value on the imaginary timeline.

time bounds

Two timepoints marking beginning and end of a time range, which can be a closed or half-open interval.
