38 Replacement of system's struct timeval to ensure we can carry 64 bit values
39 even on a platform which has 64 bits time, but only 32 bits tv_sec member,
40 notably Windows. We do use the system timeval when interfacing the C API
41 calls, though, so in a few cases, e.g. by THD::{start_time, user_time},
42 we need to convert between representations but mostly the struct is only used
43 internally by MySQL so we can use our own.
