According to my teammate `08:00:00/13:00:00` is a valid 8601 format for representing start + end time. Does anyone know how I'd parse that using kotlinx-datetime to get my start and end time... or maybe duration?

(all I want to do is see if the current local time is within that string format of start/end)

Seems like you could write a parser for the interval to split it into its one or two parts as a first step: <https://en.wikipedia.org/wiki/ISO_8601#Time_intervals>

After that you could probe the format of each part to determine its type and as to whether the built-in parser would handle it.

If it can't, you'd have to write a parser for that part yourself.

And you definitely have to write the parser for when the second part is missing values and apply to the parsed first part

There is a lot what is valid ISO :confused: <https://ijmacd.github.io/rfc3339-iso8601/>

Yeah, I just ended up doing a string split on / and then LocalTime.parse the two times.

yeah. i used to think 8601 was like a single "format", but even if you agree with your team that "we'll use 8601" you still have to actual pick a pattern
