parse ISO 8601 comma-spec'd decimal seconds

[rsk0]

ISO 8601 seems to say the decimal portion of seconds can be indicated with a comma*. At the very least I've seen Kafka server logs using them.

got a link to the spec where it says that?

Can you add a test case please?

Please pardon my not making that clear.

While I can't without paying 155 Swiss francs see the spec directly myself, Wikipedia paraphrases it thus:

A decimal fraction may be added to the lowest order time element present in any of these representations. A decimal mark, either a comma or a dot, is used as a separator between the time element and its fraction. (Following ISO 80000-1 according to ISO 8601:1-2019,[26] it does not stipulate a preference except within International Standards, but with a preference for a comma according to ISO 8601:2004.[27])

Of course! Where are my manners? Added.
