Forcing people to wait for a payday at a specified time is going to lead to users idling in the server all day, which is what happened in SA:MP a few years back when people waited for Developers and Managers+ to spam paydays via command. This won't be beneficial to anyone, and gives those in the server at those specific times an advantage over others who can't be online then.
If Argo was a community where everyone lived in the same time zone then this wouldn't be as big of a deal, but it is a worldwide community, so timezones will greatly affect the usage of this.
