I am using quartz in my project and have one cron job. The cron expression I give the trigger (CronTrigger) as the running parameter is alighnt with the pc s hardware clock. Any ideas how to tell the job to look at the software clock instead ?
例如,我有一个任期一年的工作,工作时间恰好在10时,有些工作日我们转向夏天,我希望能自动更新这项艰巨的工作。

顺便说一句,意思是改为。
该案将自动处理。
你们唯一需要小心的是,在实际转变过程中安排了工作。
In the forward shift the time goes from 1am (std) to 2am (std) to 1am (dst).
Jobs scheduled to run between 1am and 2am need to make sure they do not run twice.
退步可能产生相反的效果。 页: 1 视Quartz是如何实施的,它可以在工作间隔期间跳出工作,或在工作转变后管理所有工作。
如果它从事绝对必须从事的工作,则将其安排在转移窗口之外(临时+/1小时)。
简而言之,always use UTC for system time (and time Zone)。
很严重的是,这涉及诸如节日 Sav节式节减规则等问题,有助于确保时间上接近于单州的增长(即时间上等于“jump”后退,打破了许多对依赖时间的软件的假设),也涉及跨时区服务器和(或)用户(即地理分布的计算机和(或)用户)。
* 这里的情况,我忽略了
由于这个问题似乎与计算机系统有关,也涉及与本组织有关的工具(即cron),我认为这个问题不适合于StackOverflow.com。 请考虑将其移至。
