datetime.datetime -> struct_time
for dt in [ datetime.datetime(2011, 2, 9, 9, 0),datetime.datetime(2011, 9, 30, 9, 0),]:# Convert datetime -> struct_timetime_t = time.struct_time(dt.timetuple())
struct_time -> seconds -> struct_time
# Round-trip: struct_time -> seconds -> struct_timelocal_time_t = time.localtime(time.mktime(time_t))
获得夏时令标识符
# The answer is in tm_isdst# 夏令时标识符# 实行夏令时的时候，tm_isdst 为 正。# 不实行夏令时的进候，tm_isdst 为 0# 不了解情况时，tm_isdst()为负。print dt, bool(local_time_t.tm_isdst)
