Just gave this tool a try on our large project and loading the trace in Chrome throws:

Error: Slice Project "foo.csproj" (400) end time is before its start.

I'm not sure how to get more useful debug info to determine whether the error is in the source .binlog or in the traces from this tool (I'm assuming the latter). I tried doing a quick ctrl-f through the trace file for the affected project name to see if I could quickly spot the error but there's a million references to it since this is a somewhat large build (~140 projects).

I'm internal at MSFT so if you want to email me (same alias as here) I can share the source project or .binlog if that makes it easier to debug or I can try to capture some more info to post here if you let me know what would be useful.
