Time duration


There are two accepted syntaxes for expressing time duration.

[-][HH:]MM:SS[.m...]

HH expresses the number of hours, MM the number of minutes for a maximum of 2 digits, and SS the number of seconds for a maximum of 2 digits. The m at the end expresses decimal value for SS.

or

[-]S+[.m...]

S expresses the number of seconds, with the optional decimal part m.

In both expressions, the optional '-' indicates negative duration.

The following examples are all valid time duration:
