Global state machine should go back to Idle after user not responding for certain time
Periodic event needed for features like asking users' weight daily

Spring @Scheduled only works for cron.fixedDelay and fixedRate do not work for callback because it will do the loop again and again. Bildschirmfoto 2017-10-29 um 8.22.48 PM.PDF It seems that ScheduledExecutorService is the best implementation way for delay a method I can find.

Heroku server is using UTC time, but we can config it by 'heroku config:add TZ="Asia/Hong_Kong"'. Need to be careful when setting the cron expression.

Time zone can be set using zone field in @Scheduled annotation
