That's if you use a comma or a fullstop. With the full colon it's
interpreted as hours and minutes.
It is also acceptable to omit elements to reduce precision. [hh]:[mm],
[hh][mm] and [hh] are all used.
Decimal fractions may also be used with any of the three time
elements. These are indicated by using the decimal point (either a
comma (which is preferred ISO 31) or dot). A fraction may only refer
to the most precise component of a time representation. To denote "14
hours, 30 and one half minutes", do not include a seconds figure.
Represent it as "14:30,5" or "1430,5".
