Elasped Time Jumps in Value

[KMacros]

Versions: OpenEVSE v5 Advanced purchased Dec2018 / 4.8.0 wifi 2.7.5

I notice the Elapsed Time on the OpenEVSE tab in the Status Panel jumps up by 1 minute in value near 30 seconds and by 1 hour near 30 minute values. I suspect the code in ESP8266_WiFi_v2.x/src/html/view_models/TimeViewModel.js is rounding values rather than using floor/ceiling or simply truncating the value. I've ordered an ISP programmer to update my OpenEVSE firmware 4.8.0 to 5.0.1 and a serial interface to update the ESP8266 4.7.5 in case the web update fails so I am unable to make and verify changes at this time. I have reviewed Issue #66 and found the code which I would update Math.round to Math.trunc in lines 79, 81, and 83 to show the time without the rounding artifacts. I'm also learning my way around GitHub so I could be making mistakes about the suggested corrections. Please let me know how I should proceed in contributing to this open source project.

Note that this rounding jumps in the elapsed timer can be observed in the online simulator.

Current code :
var time = self.elapsedNow().getTime();
time = Math.round(time / 1000);
var seconds = time % 60;
time = Math.round(time / 60);
var minutes = time % 60;
var hours = Math.round(time / 60);
return hours+":"+addZero(minutes)+":"+addZero(seconds);

Suggested :
var time = self.elapsedNow().getTime();
time = Math.trunc(time / 1000);
var seconds = time % 60;
time = Math.trunc(time / 60);
var minutes = time % 60;
var hours = Math.trunc(time / 60);
return hours+":"+addZero(minutes)+":"+addZero(seconds);

Edited to add versions and simulator observation.
