Description

After creating a new repo and adding origin, I tried to lock a file via the right-click menu in Unity. The file locks successfully:

$ git lfs locks
Assets/Main.unity       Daniel Plemmons ID:7

but the lock does not display in the locks tab, and the option to unlock the file is not available in the right-click menu.

Of note is that I'm hosting my repo on VisualStudio.com through VSTS rather than GitHub.

Steps to Reproduce

1. Create new Unity Project
2. Add Unity Github addon
3. Initialize git repo via the addon.
4. Connect to new remote hosted on VSTS.
5. Save main scene.
6. Commit and push main scene.
7. Attempt to lock main scene.
8. Observe that the lock completes successfully but is not displayed in the UI and can only be unlocked via the command line.

Expected behavior:
I expect to see the locked file listed in the lock tab.

Actual behavior:
The lock tab is empty.

Reproduces how often:
100% repro rate.

Additional Information

I've compared the JSON returned by git lfs locks --json on a VSTS repo and a GitLab repo (my GitHub repo didn't support LFS locking which is confusing to me). The difference appears to be a decimal point in the final portion of the timestamp from the VSTS hosted repo.

[{"id":"7"   ,"path":"Assets/Main.unity","owner":{"name":"Daniel Plemmons"},"locked_at":"2018-06-19T16:37:28.38Z"}]
[{"id":"2375","path":"Assets/main.unity","owner":{"name":"Daniel Plemmons"},"locked_at":"2018-06-19T20:33:25Z"}]

Thanks for the healthy looking bug report @RandomOutput.

Updated with additional information regarding the timestamp format in the JSON.

[StanleyGoldman]

Thanks @RandomOutput you basically solved the problem for me.

We will probably push this in a release next week.
Thanks man.
