255 hours on timer patch

I know this is an old thread, but I've been testing this and I've discovered that it interferes with the MP cost for Step Mine. MP costs for spells in general are 8-bit values, so without this patch, since the maximum time would be 99:59, the max MP cost for Step Mine would be 199. With this patch, the maximum time is 255:59, so in theory the max MP cost would be 511; however, this is no longer an 8-bit value. It's now a 9-bit value, but the top bit gets lost. As a result, for anyone who has played for 128 hours, Step Mine now has a cost of 0 when it should be 256.
