正确的时间格式：Docker logs 的 --since 参数支持以下格式：
10m - 10分钟
2h - 2小时
30h - 30小时
2007-01-02T15:04:05 - 具体时间戳
提供多个预设选项：
2天 = 48小时
24小时
7天 = 168小时
自定义小时数
所有日志
更好的错误处理：如果保存失败，会清理空文件
Docker logs --since 支持的格式：
10m - 10分钟前到现在
1h30m - 1小时30分钟前到现在
2h - 2小时前到现在
2013-01-02T13:23:37 - 从特定时间点开始
现在脚本应该能正常工作，不会出现时间格式错误了！
