Example:

I created an xls file 'times.xls' which contains only:

10:30:40
01:56:04
12:26:44

xlsread gave me this:

0.4380
0.0806
0.5186

What does that mean? I know there's a linear equation (y = ax + b) that can representate them.... but... how does it work?

I meant 'represent', not 'representate' as above. Sorry for that.

Proportions of a day.
Multiply by 24 to get hours, 1440 to get minutes, 86400 to get seconds
from midnight.
