# due to the C types "time_t" and "struct tm".
# If that limit is exceeded, Ruby extrapolates the localtime function.
#
# The Time class always uses the Gregorian calendar.
# I.e. the proleptic Gregorian calendar is used.
# Other calendars, such as Julian calendar, are not supported.
#
# "time_t" can represent 1901-12-14 to 2038-01-19 if it is 32 bit signed integer,
# -292277022657-01-27 to 292277026596-12-05 if it is 64 bit signed integer.
# However "localtime" on some platforms doesn't supports negative time_t (before 1970).
