Storing hours, minutes, seconds, and nanoseconds from format-time-string

Storing hours, minutes, seconds, and nanoseconds from format-time-string

[Heime]

I am getting the time using the format "%FT%T.%N%z".

(format-time-string "%FT%T.%N%z" nil tzone)

From the result I need to get the hours, minutes, seconds,
and nanoseconds to store them into four numeric variables.

How can I do this from the output of "format-time-string".

You can pass the output to string-split, splitting on non-digits,
i.e. using "[^[:digit:]]" as the value of the SEPARATORS argument.

Am getting (void-function string-split) on "string-split".

It's the same as `split-string'.  The alias was introduced in Emacs 29,
so I guess you're using an earlier version.

Split the format string, i.e. use `format-time-string' several
times for each data you want to acquire ...

Since the time will change between each call, it is likely that you will 
end up with inconsistent values if you do that.

Dear Heime,

As others have already pointed out, you might benefit by reading up on 
the etiquette rules applicable when asking strangers for help on the 
internet.

Things like saying please and thank you, showing minimal effort, 
expressing the problem clearly... would go a long way in improving the 
form of your communication, and in turn in getting better and faster 
answers.

This community is very friendly and most cannot say no to an elisp 
problem, but nobody has unlimited patience.

You can use format-time-string to directly get the data you want, and 
then separate it either by using string processing, or by making the 
output a valid elisp sexp.

For example:

(split-string (format-time-string "%H %M %S %N")) ;; using string processing

(car (read-from-string (format-time-string "(%H %M %S %N)"))) ;; using 
elisp processing


Good luck.

Thibaut
