import time


def get_time_stamp():
    ct = time.time()
    print(ct)
## time.time()返回当前时间的时间戳
    local_time = time.localtime(ct)
    print(local_time)
## time.localtime(sece)返回本地时间,如果未提供参数secs或None，则使用time.time()返回的当前时间
    time.sleep(60)
    data_head = time.strftime("%Y-%m-%d %H:%M:%S", local_time)
    data_head1 = time.strftime("%Y-%m-%d %H:%M:%S")
    print(data_head)
    print(data_head1)
## time.strftime(format[, t])返回格式化后的时间，如果未提供参数t，则使用time.localtime()返回的当前时间
    data_secs = (ct - int(ct)) * 1000
    print(data_secs)
    time_stamp = "%s.%03d" % (data_head, data_secs)
    print(time_stamp)
