为什么我总遇上这种奇怪的事情——etc下的设置文件貌似都失灵了？

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.

 GNU nano 2.0.2 File: /etc/conf.d/clock

# /etc/conf.d/clock

# Set CLOCK to "UTC" if your system clock is set to UTC (also known as
# Greenwich Mean Time). If your clock is set to the local time, then
# set CLOCK to "local". Note that if you dual boot with Windows, then
# you should set it to "local".

CLOCK="local"

# Select the proper timezone. For valid values, peek inside of the
# /usr/share/zoneinfo/ directory. For example, some common values are
# "America/New_York" or "EST5EDT" or "Europe/Berlin".

#TIMEZONE="Asia/Shanghai"

# If you wish to pass any other arguments to hwclock during bootup,
# you may do so here.

# If you want to set the Hardware Clock to the current System Time
# during shutdown, then say "yes" here.

### ALPHA SPECIFIC OPTIONS ###

# If your alpha uses the SRM console, set this to "yes".
