I can explain with an example
Suppose you have multiple users and each user's limit is anticipated to be exceeded at varying times. In such an event, a command must be scripted to execute at precisely 9:00 PM UTC time, which will reset the limit for all users. This command will be programmed to run once daily to prevent server overload, as opposed to running every minute or hour and we have already multiple cron running at 12 AM UTC.
Yes, your limit will be reset at 9:00 PM.
