This seems to work with date in the past:
http https://www.w3.org 'If-Modified-Since:Sun, 7 Jan 2018 13:00:00 GMT'
My app uses the "if-modified-since" HTTP header to determine if the schedule actually changed and download the new version. If the server automatically regenerates it every x minutes, then this optimization is useless. So I would also recommend that all dynamic data should be provided in separate APIs/files.
