python3 time时间戳转换

import time

ctime = time.strftime("%Y-%m-%d %H:%M:%S")

# 先转成struct_time
ctime = time.strptime(ctime, "%Y-%m-%d %H:%M:%S")

# 再转成时间戳
ctime = time.mktime(ctime)

stamp = time.time()

# 先转成struct_time
stamp = time.localtime(stamp)

# 再转成格式化时间
ctime = time.strftime("%Y-%m-%d %H:%M:%S", stamp)
