As sc wrote, strftime() is a better solution in this case. However,
for commands for which Vim does not have an internal equivalent, use
system(), e.g.,

let stamp = system("date +%s")

That will include the trailing newline in your stamp variable. If
that's undesirable, use this instead:

let stamp = substitute(system("date +%s"), '\n', '', '')
