ISO 8601 extension: fractional days
A conservative extension of ISO 8601 to support fractional days is a fun blog post about extending the ISO format for timestamps to support fractional days in addition to fractional seconds, minutes, and hours.
Aesthetically I dislike the "T" in ISO 8601 format, but what can you do.
Fractional days allows for easier handling of the French Republican Calendar and Swatch Internet Time!
Alas:
ISO 8601 does not allow for specifying offsets from UTC in seconds (another obvious oversight).
Interesting fact:
in contrast to common scientific usage, the decimal part is recommended to be separated by a comma and not a full stop, although the latter is permitted too.
I had no idea!
Anyway, what's next - fractional months and fractional years? Why not?
