enzyme-to-json VS Spearmint

I'm using Enzyme with enzyme-to-json to do Jest snapshot testing of my React components. I'm testing shallow snapshots of a DateRange component that renders a display field with the current range (e.g. 5/20/2016 - 7/18/2016) and two DateInput components that allow selecting a Date value. This means that my snapshot contains the Dates I pass to the component both in the DateInput props and in a text representation it resolves itself. In my test I'm creating some fixed dates using new Date(1995, 4, 23).

I went down a crazy rabbit hole gathering all kinds of data and analyzing the open source projects that Codesmith has. I'm very fast and it took about 2 hours one Sunday afternoon. I logged alumni LinkedIns and GitHubs for ~200 people listed on these open source project individual websites. I found about 2/3 of people listed 6+ months of work experience on their LinkedIns as "Software Engineers" but when looking at their GitHub contributions to the projects, committed on average over 2-3 week long periods only. All of these projects had the exact same spiky patterns, it was crazy, over and over and over and over again, like this: https://github.com/open-source-labs/spearmint/graphs/contributors and over and over people listing months and sometimes years of experience on their LinkedIns.
