// Representative tests for the case of timestamps before the UTC Epoch time:
// validate the expected behaviour that "negative second values with fractions
// must still have non-negative nanos values that count forward in time"
// https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#google.protobuf.Timestamp
//
// To ensure cross-platform compatibility, all nanosecond values in these
// tests are in minimum 100 ns increments. This does not affect the general
// character of the behaviour being tested, but ensures that the tests are
// valid for both POSIX (1 ns precision) and Windows (100 ns precision).
