The ~f format specifier for SRFI-19's date->string is documented as: # ~f seconds and fractional seconds, with locale # decimal point, eg. `5.2'
Let's test that example: scheme@(guile-user)> (use-modules (srfi srfi-19)) scheme@(guile-user)> (date->string (make-date 200000000 5 34 12 26 3 2017 0) "~f") $1 = "05.2" That's not the documented format: the doc and the SRFI itself show "5.2" with no leading padding, but actual behaviour is to zero pad. There is much that is ambiguous in the SRFI's specification of ~f, but with that example it does at least seem clear that there should be no padding there. -zefram
