Can Zabbix UI display sub-second (ms/ns) timestamps for history.push items?

[h0ng]

Hi all,

I’m currently using the history.push API to send high-frequency metrics to Zabbix, and I’m including both the clock (in seconds) and ns (nanoseconds) fields to preserve full timestamp precision.

Here’s a simplified example of what I’m sending:

{
  "host": "pi",
  "key": "u",
  "value": 1.829,
  "clock": 1747284947,
  "ns": 829000000
}

I’ve confirmed via the API and database that Zabbix stores the full nanosecond precision correctly, but in the Zabbix UI (Monitoring → Latest data or history view), the timestamp always displays in seconds only, like:

2025-05-15 07:55:47

Is there any way to make Zabbix show sub-second precision (e.g., .829) in the UI?
This would help verify high-frequency data order visually without relying on API or SQL lookups.
If not currently possible, are there any frontend workarounds, dashboard tricks, or plans to support this in future versions?
