I also encounter this bug. Is there any easy workaround?

[smargoli2]

Still dealing with this, please advise

[Jookus]

Any news on this?

[midi-red]

I solved this issue by changing threeten lib, compiled it and add it to my project separately. It is an ugly workaround but it looks like amazon has not fixed the issue.

[smargoli2]

@midi-red , Can you give more details? I am using C# so need more info for how to implement for myself...

[Jookus]

I finally found a workaround for the Java SDK, maybe that works for your sdks too?

This is a very old issue that is probably not getting as much attention as it deserves. We encourage you to check if this is still an issue after the latest release and if you find that this is still a problem, please feel free to open a new issue and make a reference to this one.
