[New-bugs-announce] [issue19339] telnetlib: time.monotonic() should be used instead of time.time() for timeout

[STINNER Victor]

New submission from STINNER Victor:

While reading the patch attached to #19170, I saw that telnetlib uses time.time() to compute a timeout. This is wrong: the system clock may jump forward or backward (ex: summer/winter time, NTP adjust, manual clock change by the administrator, etc.).

time.monotonic() should be used instead. I will work on a patch when #19170 will be fixed (just to avoid conflicts).
