Hello,

There seem to be a bug that was reintroduced in Helm3

Running helm package mychart/ -d ./ produces a .tgz archive. However, when extracting it...
tar -xzf mychart.tgz I get warning such as
tar: mychart/Chart.yaml: implausibly old time stamp 1969-12-31 19:00:00

This is happening in both 3.0.0 and 3.0.1.
It also seem to have been fixed last year
#4158

I guess this comment was forgotten ^^
