On sparc64, suseconds_t is of type i32 while tv_sec is of type time_t
which itself is of type i64 which causes the build on sparc64 to fail:
error[E0308]: mismatched types
--> src/lib.rs:210:30

210 | tv_sec: tv_sec + tv_usec / MICROS_PER_SEC,
| ^^^^^^^^^^^^^^^^^^^^^^^^ expected `i64`, found `i32`
error[E0277]: cannot add `i32` to `i64`
--> src/lib.rs:210:28

210 | tv_sec: tv_sec + tv_usec / MICROS_PER_SEC,
| ^ no implementation for `i64 + i32`

= help: the trait `Add<i32>` is not implemented for `i64`
= help: the following other types implement trait `Add<Rhs>`:
`&i64` implements `Add<i64>`
`&i64` implements `Add`
`i64` implements `Add<&i64>`
`i64` implements `Add`
The type mismatch for suseconds_t is a result of binary compatibility
with Solaris and cannot be changed as it's part of the ABI. Since the
values for suseconds_t never exceed 32-bit boundaries, it's not really
a problem and we can safely cast tv_usec / MICROS_PER_SEC to time_t to
fix the build on sparc64.
