Do you mention this because this is a new problem that didn't exist in
previous releases?

Since /var/log/wtmp's structure doesn't include timestamps, all times in
this file must be written in UTC.  Is your system clock set in local
time instead of in UTC?

Checking recent reboots on my 14.10 system with 'utmpdump
/var/log/wtmp.1' shows correct times:

[2] [00000] [~~  ] [reboot  ] [~           ] [3.16.0-16-generic   ] [0.0.0.0        ] [Mon Sep 22 15:00:50 2014 PDT]
[1] [00050] [~~  ] [runlevel] [~           ] [3.16.0-16-generic   ] [0.0.0.0        ] [Mon Sep 22 15:00:50 2014 PDT]

Confirmed against /var/log/kern.log that this is the time of the boot:
  Sep 22 15:00:49 virgil kernel: [    0.000000] Initializing cgroup subsys cpuset

last -f /var/log/wtmp.1 shows similarly correct information:

reboot   system boot  3.16.0-16-generi Mon Sep 22 15:00 - 12:32
(10+21:31)

So I can't reproduce the problem you're describing.

Title:
  /usr/bin/last is using UTC rather than local time for login

Status in “sysvinit” package in Ubuntu:
  New

Bug description:
  I upgraded from 14.04 to 14.10.  When I run /usr/bin/last, which
  relies on /var/log/wtmp, I get the following output (note:  I replaced
  my login name with XXXX):

  XXXX     pts/8     :0               Thu Oct  2 20:40   still logged in   
  XXXX     pts/2     :0               Thu Oct  2 20:36   still logged in   
  XXXX     pts/2     :0               Thu Oct  2 18:55 - 20:30  (01:34)    
  XXXX     :0           :0               Thu Oct  2 18:54   still logged in   
  reboot   system boot  3.16.0-20-generi Thu Oct  2 22:54 - 20:41  (-2:-12)   
  XXXX     pts/9     :0               Thu Oct  2 18:38 - 18:52  (00:14)    
  XXXX     pts/0     :0               Thu Oct  2 18:35 - 18:53  (00:17)    

  Note that for the XXXX login, the session's start and stop time are
  both shown in local time.  However, for the reboot line, the start
  time is shown in UTC (i.e. Greeenwich) time and the current time is
  shown in local time, which gives rise to the negative elapsed time.

  I tried emptying the /var/log/wtmp file and rebooting.  No luck.

  Possibly wtmp is being written to before the time zone can be
  established.  My time zone is EDT (US/Eastern, same time zone as New
  York).

  When I run the linux "date" command, the time zone is shown correctly.
