In Germany the comma is the decimal separator, so this doesn't look like two
words to my eye. However, the culprit is
https://en.wikipedia.org/wiki/ISO_8601
"""
A decimal mark, either a comma or a dot (without any preference as stated in
resolution 10 of the 22nd General Conference CGPM in 2003,[16] but with a
preference for a comma according to ISO 8601:2004)[17] is used as a
separator between the time element and its fraction
