Yes, problem of mine. Sorry for this issue.

Amazing trick, but I can't realize how it works.
Please, could you give me some documentation for this method?

Hi!

There is a bug in this kata.

For example,

"The output expect Peter is 26 years, 9 months and 23 days old but it returns Peter is 09 years, 27 months and 1990 00:00:00 days old
Expected string length 43 but was 55. Strings differ at index 9.
Expected: "Peter is 26 years, 9 months and 23 days old", ignoring case
But was: "Peter is 09 years, 27 months and 1990 00:00:00 days old"

Hi!

I think, something wrong with this kata:

Test Results:
HumanReadableTimeTest
HumanReadableTest
Expected string length 15 but was 8. Strings differ at index 1.
Expected: "05:0-55:0-14695"
But was: "00:00:05"
