You need to post an excerpt ... in code-tags, please ... of your actual source-code. Also note the return-code from each call and the contents of the parameter-structures before and after each call.
However, when dealing with intervals of this length, I would suggest using other facilities – such as cron or systemd "events." There's really no point in "waiting around" (literally ...) "all day," when there are already other daemons doing that.
