#TASK SCHEDULER SYNC ACROSS TIME ZONES CODE#

In short, email programs scheduled with Recipient Time Zone need to start running at the scheduled time in the earliest time zone (i.e., where it reaches midnight first) in order to accommodate every time zone. This means that if you’re in America/Los Angeles and want to enable both Head Start and Recipient Time Zone, you need to schedule the program 34 hours in advance. So, to enable both Head Start and Recipient Time Zone, email programs need to be scheduled at least 12 hours ahead of the scheduled time in UTC +14:00. So what does that mean for Recipient Time Zone? Recall that when Recipient Time Zone is enabled, we start running the email program at the scheduled time in the earliest time zone (UTC +14:00). Our existing Head Start feature requires the program to be scheduled at least 12 hours in advance. Now, let’s talk about how Head Start works with Recipient Time Zone. There may be people who qualify for your smart list in every time zone across the globe, so starting in the earliest time zone allows us to deliver the email at the scheduled date/time to all recipients in their respective time zones. In this case, the program will start running at the scheduled time in the earliest time zone in the world (UTC + 14:00). In this second scenario, you approve an email program with Recipient Time Zone enabled and a scheduled delivery time that’s more than 25 hours in the future. Recipients will still receive emails based on the Time Zone Settings you choose. Let’s look at a few reasons why you should avoid the date and time classes in the java.util package when developingĪpplications.Although the program will start the process of sending emails in 15 minutes, emails won’t be delivered at that time. Drawbacks of Legacy java.util Date Classes We will deep-dive into various aspects of handling time zones in the further sections. Operations around dates, times, and time zones can be confusing and prone to errors.

That observe DST will move from Australian Eastern Standard Time (AEST) to Australian Eastern Daylight Time (AEDT). For instance, in Australian summer, the states

To account forĭST changes, countries or states usually switch to another time zone.

Daylight Savings Time (DST) is the practice of setting clocks forward by one hour in the summer months and backĪgain in the fall, to make better use of natural daylight.

It is a universally preferred standard that can be used to

Universal Coordinated Time (UTC) is not a time zone.

However, the United Nations officially adopted UTC as a standard in 1972 since it was more accurate than GMT for Recommended as the prime meridian of the world in 1884 and eventually became the basis for a global system of time zones.

Greenwich Mean Time (GMT) is a time zone used in some parts of the world, mainly Europe and Africa.

This article is accompanied by a working code example on GitHub. In this article, we will try to understand the options available in Java and apply them in the context of a SpringĪpplication to effectively handle time zones.

Handling date and time operations consistentlyĪcross multiple layers of an application can be tricky. It is common to encounter applications that run in different time zones.
