A system like this will give them a reward every time they log in after 24 hours, and then update the time after every day they log in, the only problem is that on large servers, this could end up with hundreds or even thousands of variables, so it may be a better ideas to store this in a file or the player's PDC.

on join:
    {join::%player's uuid%} is not set:
        set {join::%player's uuid%} to now
        stop
    if (difference between now and {join::%player's uuid%}) is less than 24 hours:
        stop
    set {join::%player's uuid%} to now
    set short tag "days" of player to 0 if byte tag "days" of player is not set
