Is html5 interfering with time of day clock?
XP professional, Dell E5400, the time of day loses several seconds after playing html5 I think. Is that possible?
Something at real time priority perhaps.

What is 'time of day?' An add-on? Another program?
Is it set to sync with an atomic clock?
The displayed time of day (adjusted as necessary once a week by XP) loses a few seconds after playing html5 videos. Apparently some cycles are lost, and I was thinking by a lost interrupt-driven addition when an equally high priority takes over the bus in html5.
This is not good, if I'm correct about the cause.
That can happen in games. It would be a windows xp issue. If you are wanting to see if Firefox is the issue can try in Safe Mode SAFE MODE
- https://support.mozilla.org/kb/Safe+Mode
- https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
In Firefox Safe mode these changes are effective:
- all extensions are disabled (about:addons)
- default theme is used (no persona)
- userChrome.css and userContent.css are ignored (chrome folder)
- default toolbar layout is used (file: localstore-safe.rdf)
- Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
- hardware acceleration is disabled (Options > Advanced > General)
- plugins are not affected
- preferences are not affected
TEST
If it is HTML5 then does not matter what you do.
Please let us know if this solved your issue or if need further assistance.
As Fred asked can you make sure that Windows XP is set to check with Atomic Clock rather than Microsoft please.

Maybe when things are pegging your cpu it could cause it to lose time a bit. Another reason for losing time can be due to the battery on motherboard being weak.
WinXP does not really support HTML5 as Windows Vista and later does as Microsoft does not provide media feature packs and codecs for WinXP.
Without workarounds at least two check marks should be red on https://www.youtube.com/html5/ as all should be blue ideally.
It won't depend on time sync source or processor pegging. The time sync is weekly and adjusts the clock and clock speed to make it better; and processor pegging won't affect the clock interrupt, which takes over whatever is running to raise the count by one.
Unless whatever else is running is at the clock interrupt priority and so blocks it (by getting a second clock interrupt which wipes out the first, probably) and causes it to miss a count now and then.
This happens during a video, so some rule is being violated.
Hi, Please uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's(Win10)) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

- https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer
Reinstall with Current Release Firefox 52.7.1ESR with a Full Version Installer
fyi :
Please let us know if this solved your issue or if need further assistance.

It does not seem to happen with only one CPU (of dual core) enabled.
Slight possibility is that it's from a process identifying bug that turns up in Cygwin, which also happens less with one CPU core. Not that it's that often even with dual core. So a slight possibility.
