**time -- relative elapsed time (in seconds)

DESCRIPTION

The **time representation is used to represent cumulative time (from some arbitrary moment deemed "time zero") to the onset of the current moment. A typical use for **time is to represent the elapsed time from the beginning of a work (in seconds). Data tokens in **time consist simply of numbers of seconds, with an optional decimal value. The **time representation has no provision for representing "hours" or "minutes".

Barlines are represented using the "common system" for barlines -- see barlines.

FILE TYPE

It is recommended that files containing predominantly **time data should be given names with the distinguishing `.tim' extension.

SIGNIFIERS

The following table summarizes the **time mappings of signifiers and signifieds.

0-9	decimal values
.	fractional second delimiter; null token
=	barlines
==	double barline

Currently, no special-purpose Humdrum commands produce **time as output, or process **time encoded data as input.
