We have to look at these timestamps
and say, OK, what does this mean?
You're going to find where some tools will show you
1/1/1970 or 1/1/2001.
And people's first response is, the tool is bad.
There's a bug in the tool.
But it's actually not.
It is counting the number of seconds since 1/1/2001 for Mac
and the number of seconds since 1/1/1970 for Unix.
So if the number-- if the value is 0 in that column--
meaning, if you're looking at these update times,
and one of these was 0--
so this one right here that I'm highlighted on, if that was 0,
that would show as 1/1/1970, which is actually correct
because it's 0 seconds from 1/1/1970.
In your lab, if that's happening, and it's annoying,
I want you to make it go away.
I want you to think like a developer
and what these vendors should be doing
to make that timestamp go away.
You can't do that.
This is a good summary here of the different timestamps.
Chrome is the nightmare.
If it looks like Unix, but doesn't fit the bill,
it's most likely Chrome.
We are going to see Chrome timestamps in section 5.
