First of all: Amazing support! 
Timezone is ok for me. If fixed it already using the one cron.js file and only execute it in specific NODE_ENV environments. That’s ok. Having different config/env/** folders for everything would be cleaner in my opinion.
And this should be added to the docs. Since cron.js lives inside /config folder the following statement in the docs is confusing:
When starting Strapi with NODE_ENV=production it will load the configuration from ./config/* and ./config/env/production/*. Everything defined in the production config will override the default config.
Especially the Everything defined in the production config part.
Thanks again and keep up the great work!
