[apache/incubator-teaclave-sgx-sdk] How to correctly port third party crates like time (#223)

[Rust SGX SDK v1.0.4 Release Notes](https://github.com/apache/incubator-teaclave-sgx-sdk#v104-release)  said 

> New third party libraries bit-vec, chrono, erased-serde, fxhash, nan-preserving-float, num-bigint, quick-error, raft-rs, time, webpki-roots, yasna.

 This means that we can port third party crate like crate time in the rust-sgx. But I’m confused how to express correctly in the Cargo.toml. I wrote in the Cargo.toml 
```
[dependencies.time]
version = "0.1"
default-features = false
```

And my code is 
```
extern crate time;
```
But got error like
```
error: duplicate lang item in crate `std` (which `time` depends on): `f32_runtime`.
  |
  = note: the lang item is first defined in crate `sgx_tstd` (which `helloworldsampleenclave` depends on)
```
When we import the third party, are there any requirement?And how we define the requirements if I want to import other party? 
Thanks for your reading and looking forward to your reply:)

Here is a ported crate time :  https://github.com/xuperdata/untrusted-time

Thanks.

@RMheng, @duanbing, we are working on a separate project called "crates-sgx" (https://github.com/universal-secure-computing-community/crates-sgx) which is a monorepo of all Rust crates ported for Teaclave SGX SDK targeting the Intel SGX platform.

In this project, we want to establish a clear porting process and accept high quality SGX crates. We have several people working on this. Feel free to contribute if you are interested. Thanks.
