Mine Time
A time-based pass system for the Timed Mines: you need a positive time balance to enter any mine, and that balance only drains while you're actually inside one.
How It Works
You start with zero mine time. Buy a voucher with /minevoucher buy <tier> - vouchers come in 5, 10, and 15-minute tiers, purchased with money. Buying one gives you a physical, right-clickable item; right-click it to redeem the time onto your balance. If you still have time left, you'll need to use it up before redeeming another voucher.
You can buy up to 3 vouchers per rolling 24 hours, counted from each individual purchase - so it's not a fixed daily reset, just a sliding window.
You can't walk into a mine's area with zero balance - an invisible barrier stops you at the edge, and teleporting in some other way won't get around it either.
Once you're inside a mine, your balance ticks down by the second. A boss bar shows how much time you have left, and you'll get a warning when you're down to your last 30 seconds. If your balance hits zero while you're still inside, you're teleported back to spawn with a "no mine time" message - so it's best to keep an eye on the boss bar and head out before that happens.
/minearea opens a menu showing every mine's reset countdown, how full it currently is, and how much of its ore is still left to mine, along with buttons to buy vouchers and teleport straight to a mine (you still need a positive balance to teleport in).
