* Need to be careful about comparing strings, because {@link DecimalFormat} is used and relies upon the default locale. What
* we do know is:
* <ul>
* <li>the hours will be at least 2 digits (zero-padded at beginning);</li>
* <li>the minutes will be 2 digits (zero-padded at beginning);</li>
* <li>the seconds will be formatted according to "00.000,###" using DecimalFormat and the default locale (which may use a
* different decimal point delimiter than '.') and where the ',' is only used if there are more than 3 digits used in the
* fractional part;</li>
* <li>the hours, minutes and seconds will be delimited with a ':';</li>
