Fix milliseconds handling in intervals (#51675) (#52224)
Browse files Browse the repository at this point in the history 
This fixes:

- the parsing of milliseconds in intervals: everything past the . used to be converted as-is to milliseconds, with no normalisation of the unit; thus, a value of .23 ended up as 23 millis in the interval, instead of 230.
- the printing of a trailing .0, in case the interval lacks the fractional part;
- tests generating a random millisecond value used to simply print it in the string about to be evaluated without a necessary front-filling of 0[s], where the amount was below 100/10.

(The combination of first and last issues above, plus statistical "luck" made the incorrect handling pass the tests.)

(cherry picked from commit 4de8c64)
