influxdb 1.77 Unix time to RFC3339( Normal time) in SQL query

Dear Sir
I met a problem when I want to get normal time like picture demonstrate
SQl:

**_Select
Spread("Advancenumber") as rings,
"time" as Day
FROM "Sensors"
Where "Advancenumber">0
Group By time(1d)_**

Return time format is Unix (ms) like 1604188800000
Would you please give me some tips how to transform Unix time (1604188800000) to normal time like (2009.02.14 00:31:30)

Thanks

The report provides a SQL query and an attached screenshot, but names no repository file, test, or entry point. Start by determining whether InfluxDB supports the requested Unix-millisecond to RFC3339 conversion, and consider the issue resolved only when the supported query syntax or limitation is documented.
