Bug#1053872: systemd with high load after 19-01-2038

[Tony de Goede]

Package: systemd
Version: 252.12-1~deb12u1
Severity: serious
Justification: linux system unstable

Dear Maintainer,

   When setting the time to 19 Jan 2038 3:14 GMT using "date 011903142038"
the systemd gets high load.
   At 7 seconds after 3:14 the date is correct in the kernel but systemd
   get high load.
   After disable systemd-journald the error from systemd is reported to
   console: "Time has been changed"
   Inspection of the systemd code, I found lines in manager.c and others
   calling timerfd_settime using struct itimerspec with seconds set to
TIME_T_MAX.
   The define TIME_T_MAX is 0x7fffffff which is used to set a time which
   blocks the call until an event triggers the timer. The TIME_T_MAX is
19/01/2038 3:14:07.
   After 2038 this define does not work for ABS_TIME in settime.
   Implementation of a blocked timer is wrong using this TIME_T_MAX in
ABS_TIME value.
   Create a timeout relative to current time or calculate a better
   absolute time.
