# It is initialized to the current system time if no argument is given.

# *Note:* The new object will use the resolution available on your

# If one or more arguments are specified, the time is initialized to the
# specified time.
#
# +sec+ may have subsecond if it is a rational.
#
# +tz+ specifies the timezone.
# It can be an offset from UTC, given either as a string such as "+09:00"
# or a single letter "A".."Z" excluding "J" (so-called military time zone),
# or as a number of seconds such as 32400.
# Or it can be a timezone object,
# see {Timezone argument}[#class-Time-label-Timezone+argument] for details.
