#OBS: por usar um servidor sntp, a confiabilidade da hora pode não ser a esperada.

# Script to set Linux hardware clock (/usr/sbin/hwclock or /sbin/hwclock) from an NTP
# time server.   Run as "setclock.py" to simply print the time from
# the NTP server.  Run as "setclock.py --set" to set the Linux
# hardware clock (as the super user, of course).

# Based on Simon Foster's simple SNTP client from ASPN Python cookbook.
# Adapted by Paul Rubin; this script lives at:

time_server = ('time.apple.com', 123)
# time.apple.com is a stratum 2 time server.  (123 is the SNTP port number).
# More servers info can be found at
#
#   http://www.eecis.udel.edu/~mills/ntp/servers.htm
#
# Note it's considered antisocial to use a stratum 1 server (like NIST)
# for purposes like this which don't need extreme accuracy (i.e. syncing
# your own big NTP network).  See www.ntp.org for more info.
#
# You could also use time.windows.com (Microsoft server) which syncs
# all Windows XP machines everywhere, so it can presumably handle lots
# of clients.

# number of seconds between NTP epoch (1900) and Unix epoch (1970).
