guessed as follows:
If `user-emacs-cache-directory' is set (e.g. by the
`xdg-paths.el' package available from
https://github.com/tomprince/xdg-paths-el), the timestamp file is
opened from there. Otherwise, it will be read from
`user-emacs-directory'
If NO-SAVE is 'nil', the current date will be saved to the
timestamp file.
The return value of this function will be 't' if the timestamp
file contains todays date, 'nil' otherwise."
