# STATUS current
# DESCRIPTION
# "A date-time specification.
#
# field octets contents range
# ----- ------ -------- -----
# 1 1-2 year* 0..65536
# 2 3 month 1..12
# 3 4 day 1..31
# 4 5 hour 0..23
# 5 6 minutes 0..59
# 6 7 seconds 0..60
# (use 60 for leap-second)
# 7 8 deci-seconds 0..9
# 8 9 direction from UTC '+' / '-'
# 9 10 hours from UTC* 0..13
# 10 11 minutes from UTC 0..59
#
# * Notes:
# - the value of year is in network-byte order
# - daylight saving time in New Zealand is +13
#
# For example, Tuesday May 26, 1992 at 1:30:15 PM EDT would be
# displayed as:
#
# 1992-5-26,13:30:15.0,-4:0
#
# Note that if only local time is known, then timezone
# information (fields 8-10) is not present."
