`show pppoe-server sessions` uptime format is ambiguous (`1.06:16:20` vs `15:42:11`)
Closed, WontfixPublicBUG

Description

Version: VyOS 2026.09.16-0028-rolling (amd64).

Summary: The uptime column of show pppoe-server sessions renders sessions older than one day as D.HH:MM:SS (e.g. 1.10:32:56) and sessions under one day as HH:MM:SS (e.g. 21:37:09). The dot separator is undocumented and easy to misparse.

Evidence:

ifname |  username   |     ip       | ... |   uptime
ppp6   | 18054251887 | 10.254.1.207 | ... | 1.10:32:56     <- 1 day 10h 32m
ppp4   | 13570358624 | 10.254.9.202 | ... | 21:37:09       <- 21h 37m (same field, different format)

Impact: a downstream management tool parsing this column treated every session older than 24h as "0 seconds online" -- 18 of 28 live sessions were displayed with a bogus uptime, which severely misled operations.

Expected: unambiguous rendering (e.g. 1d10:32:56) or explicit documentation of the format.

Suggested fix: format the column in the op-mode script, or document it in the CLI reference.

This behavior has always been in the upstream, and many users are familiar with this format. So it is not a question of the op-mode scripts that we use.
For parsers, the uptime-raw format probably should be used. https://github.com/accel-ppp/accel-ppp-ng/blob/1210a0b84b7c22837676571cae42522d6f265873/accel-pppd/cli/show_sessions.c#L513
I do not see any bugs here, and I am closing the task.
