---@type number
--- A simple timer. Ticks upwards at a rate of 1/sec.
---
--- **The start time is undefined!** This uses `os.clock()`, meaning this will be inconsistent between modfile starts.
---
--- It's recommended to only use this for eg. `math.sin`, rotations, and other similar visual effects. If you want a proper timer, see `b`.

--- The amount of beats that have passed since the start of the file.

--- Equivalent to a modfile-sandboxed `_G`, similar to Mirin's `xero`. You shouldn't need this; and if you do, *what are you doing?*
