fix time diff

[klensy]

Currently at https://perf.rust-lang.org/status.html
time shown as

No current collection in progress. Last one finished at 2/26/2021, 7:30:10 PM local time, -14m0-31s ago.

so fixing last portion to real time diff.

Hm, have you tested this locally? This has bothered me for a while, but it feels like moving the division isn't the right fix - I'd expect flipping end and the current time to be closer to the right fix?

You can check values: end in milliseconds, new Date() in milliseconds too, but new Date()/1000 - end will be negative, you can check that in js debugger.

[klensy]

format_duration(Math.trunc((new Date()/1000 - end)))
" -55m0-45s"

format_duration(Math.trunc((new Date() - end)/1000))
"1h20m57s"

Hm, ok. Thanks. CI is a different bug, unrelated to this, so going to go ahead and merge.
