#设a为字符串import timea = "2011-09-28 10:00:00"#中间过程，一般都需要将字符串转化为时间数组time.strptime(a,'%Y-%m-%d %H:%M:%S')>>time.struct_time(tm_year=2011, tm_mon=9, tm_mday=27, tm_hour=10, tm_min=50, tm_sec=0, tm_wday=1, tm_yday=270, tm_isdst=-1)#将"2011-09-28 10:00:00"转化为时间戳time.mktime(time.strptime(a,'%Y-%m-%d %H:%M:%S'))>>1317091800.0#将时间戳转化为localtimex = time.localtime(1317091800.0)time.strftime('%Y-%m-%d %H:%M:%S',x)>>2011-09-27 10:50:00
