有什么问题?你的代码有效

编辑:

这段代码在终端中运行良好——正如@ForceBru 提到的,如果你在脚本中运行它,你将需要使用打印功能来显示结果 strftime

from time import gmtime, strftime   

print(strftime("%Y-%m-%d %H:%M:%S", gmtime()))                                                                 
> '2019-02-14 13:56:02'                                                                                        

print(strftime("%H:%M:%S", gmtime()))  
> '13:56:16'

您的原始代码是正确的,但缺少打印语句。

from time import gmtime, strftime
print (strftime("%Y-%m-%d %H:%M:%S", gmtime()))
# output

以下是获取协调世界时 (UTC)/格林威治标准时间 (GMT) 时间戳的其他一些方法。

from datetime import datetime
from datetime import timezone

current_GMT_timestamp = datetime.utcnow()
print (current_GMT_timestamp)
# output
2019-02-14 14:56:18.827431

# milliseconds removed from GMT timestamp
reformatted_GMT_timestamp = datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S')
print (reformatted_GMT_timestamp)
# output
2019-02-14 14:56:18

# GMT in ISO Format
current_ISO_GMT_timestamp = datetime.now(timezone.utc).isoformat()
print (current_ISO_GMT_timestamp)
# output
