trends fetch

[jmir]

The timestamp is not exactly UTC but the current timestamp is used as if it was a UTC time. This is needed for days start at 0:00, otherwise the daily data calculation will be wrong.

Use this to convert trend timestamp to a formatted date string:

Code:

os.date('!%d %m %Y %H:%M',value[1])

So if I understant it, inside rrd you're storing a "local timestamp" like this:
  if now it's "04/September/24 14:00:00 GMT+02:00 DST" you store this timestamp 1725451200+2*3600

Isn't it?
