That first output is from this time() call, and so it's assigning time() to $t. The time() function returns an integer value, which is the number of seconds since January 1st, 1970. And this is, of course, inherited from the underlying C standard library, which is based on Unix, and so this is based the Unix epoch. This is really excellent for doing time on math, so, for example here, if I wanted to add four years to this, right? I would say, $t += , and let's see, 60 seconds times 60 minutes times 24 hours times 365 days, and I know there's probably a leap year in there, and so I'm gonna say times 4 years and plus 1, and actually that is, that's gonna be plus one second, not plus one day, and so I'm gonna want this here,…
