Additional context
I did a bit of trying to track down the problem in hopes of doing a PR instead of this, but I couldn't fix it myself. Here's what I found in my testing tonight though.

The file glances/outputs/static/js/filters.js was giving me a couple problems. The timemillis function seemed to be problematic. I don't have a great understanding currently of how the web side of Glances interacts with itself, but I did some testing with what I believe are the values that were being given to it, coming from the API at /api/4/processlist. Specifically, I grabbed one process' cpu_times values, which was:

{
  "user": 4229.49,
  "system": 1055.1,
  "children_user": 962.61,
  "children_system": 70.49,
  "iowait": 0
}

Running Node and passing that object to timemillis returned 0. It seemed to me that the for loop was failing to iterate over the object. Changing timemillis to iterate over the keys (for (var key in array)) got me an actual number out of it.

Looking then at timedelta:

• d ends up representing 1970-01-01T00:00:00.000Z when sum is 0
• doy results in 365
• Return value ends up as:

{
  "hours": 8736,
  "minutes": 0,
  "seconds": 0,
  "milliseconds": 0
}

My guess is that the math around Date is not acting as expected, but that's all I've got with my current understanding of the code.

I don't currently know where else those two functions are used, if anywhere, but I'm planning to give more of a look later. Assuming I don't find anything else relying on these, I'll try gutting and remaking those functions, and opening a PR after some testing if it turns out well.
