Question

我使用crontab.guru创建了一个非常简单的CRON表达式，每天在3:15（AM）执行所需的行为，结果如下：15 3 * * *

对我来说不幸的是，Azure Portal这不起作用，但如果我向我的表达式0添加一个前导0 15 3 * * *，Azure将接受它，而{{1}会告诉我这是错的。根据{{1}}的规范是：分钟工作日的分钟日期。

问题..

从何处出现差异？
微软是否以传统方式拥有专有权实现领先零？
如果标准是分钟日期月工作日，那么该怎么办？领先的零描述？

查看文档：

CRON表达式由6个字段组成：{second} {minute} {hour} {day} {month} {week of the week}。

所以第一个0描述秒。

Azure WebJob不接受有效的（？）CRON表达式
