my blogthing

i sometimes have the displeasure of interacting with eduroam in the following, horrible way:

• i fail to charge my laptop overnight, and start it while at the eduroam location from 0% battery
• because newer thinkpads have removed CMOS batteries, the system time is reset to one in the past
• now...
  • because eduroam relies on TLS-based authentication (and that depends on the time), i cannot log in to eduroam
  • because i use systemd-timesyncd, i cannot set the time manually
  • because the public wifi at the same location filters out ntp packets, syncing the time through it is infeasible

this is annoying.

working solutions

hotspot

• open a hotspot on my phone and connect
• systemctl restart systemd-timesyncd
• connect

set time manually

• systemctl stop systemd-timesyncd
• timedatectl set-time <time from my wristwatch>
• connect
