Function ion_c_sys::ion_timestamp_instant_equals

pub unsafe extern "C" fn ion_timestamp_instant_equals(
    ptime1: *const ION_TIMESTAMP, 
    ptime2: *const ION_TIMESTAMP, 
    is_equal: *mut BOOL, 
    pcontext: *mut decContext
) -> iERR

Compare timestamps for instant equality only (i.e. precision and local offsets need not be equivalent). NOTE: if this has any use externally, it could be exposed. If not, it should be removed.
