Bug report summary

In dashboard chart display, the time since midnight and till 01:00 is reported as 24:01:30 and so on instead of 00:01:30:

I see it in most recent nightly (v1.23.1-77-g013c9da6) but not in v1.23.1 stable and it affects all displayed charts, not only one.

OS / Environment

Linux pve 5.4.44-2-pve #1 SMP PVE 5.4.44-2
Debian GNU/Linux 10 (buster) (Proxmox)

Netdata version

v1.23.1-77-g013c9da6

Component Name

web (probably)

Steps To Reproduce

Not sure if this is relevant but after I have installed nightly version I have deleted all dbengine data so it was a clean start.

My configuration has nothing special:

[global]
        history = 90000
        memory mode = dbengine
        page cache size = 512
        dbengine disk space = 2048
        access log = none

[plugins]
        ebpf = no
        ebpf_process = no

Expected behavior

Display time since midnight properly, not as 24:..

I upped the prio to medium, this shouldn't be hard to fix.

This is related to local browser settings, timezone and language.
@aldem Do you still experience this issue? If yes, can you please share which timezone settings to your have in the Dashboard? It's under settings/locale/"Show browser local time or server time?" section

Can you also tell which browser are you using and check your detected language, by running navigator.language in browser console?

@jacekkolasa Yes, I still do (at least in 1.26 stable, didn't try nighties yet).

Indeed, the problem is probably browser related - I have no issue with Firefox but it is present in Chrome and Edge (all most recent). Language is detected as "en" (Edge) and "en-US" (Chrome). Timezone is set to server which is in turn set to CET (though this is also client's side time zone).

i need to prioritise it lower since i cannot recreate it and perhaps that issue doesn't cause that many problems..

@apostolidhs told me that this issue goes away with Charts 2.0, which is about to be released on the cloud. It will take some more time to bring it to the agent.

Fix for Charts 1.0 on the agent included in v2.20.0
