Introduction

TDA extends the DA file format with a time stamp field.

Basic structure

If the first byte of the file is a number sign (#), all bytes up to and including the first newline are ignored.

A TDA file consists of a sequence of

	<timestamp> <name>:<type><value>

where

Timestamp

<timestamp> must start on the first byte after a newline.

<timestamp> is an ASCII decimal number. The number may be negative, in which case it is prefixed by a hyphen (ASCII 45). The number may optionally have a fractional part, in which case a period (.) is used as a separator between the integral and fractional parts.

<timestamp> specifies SI seconds since 00:00:00 UTC on January 1, 1970, not counting leap seconds.

<timestamp> is separated from <name> by a single space (ASCII 32).

Name, Type and Value

The <name>, <type> and <value> fields are described in the DA file format specification.

Example file
