python time 获取毫秒级时间戳

1、time 获取秒级时间戳，格式化显示

import timets = time.time()print("time:", ts)  # 原始时间数据，单位为秒# time.strptime 只支持到秒级别！dt = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(ts))  # 转 UTC时间，精确到秒print("time UTC str:", dt)print("time UTC ms str:", dt + f".%.3f" % ((ts - int(ts)) * 1000))  # 显示毫秒和微秒

结果：

time: 1685594545.0012841time m str: 2023-06-01 12:42:25time ms str: 2023-06-01 12:42:25.1.284

2、datetime 获取当前日期时间

# 获取含微秒的日期时间 print(dt_ms)dt_ms = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S.%f')print(dt_ms)

结果：

2023-06-01 12:45:13.345816

3、日期时间之间的转换

3.1、字符串转 time

dt = '2018-01-01 10:40:30'ts = int(time.mktime(time.strptime(dt, "%Y-%m-%d %H:%M:%S")))print (ts)=>1514774430

3.2、字符串转 time

ts = 1515774430dt = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(ts))print(dt)=>2018-01-13 00:27:10

3.3、示例

ts = time.mktime(time.strptime("2023-06-05", "%Y-%m-%d")) # 1685894400.0time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(1685894400.0)) # 2023-06-05 00:00:00'
