Unable to parse terminationTime from TerminateProcess message

[j1mmie]

I know this repo is rather old, just saving this issue here for posterity. I hope I can submit a PR for it some day.

I'm seeing this error on live servers in GameLift:

It appears that terminationTime is assumed to be a Long at this point. I'm not sure what the value actually is, but there could be some additional checks / conversions to avoid this error
