Events: cannot specify timezone for Schedule cron

[maxhayward]

Describe the feature

In the console, when creating a Rule with an Event schedule, I have the option to use UTC or 'Local time zone'.

I can't seem to find a way of specifying this in CDK. It would be helpful if this is possible.

Here's my current implementation - if there's something I can add to this, that would be great.

const rule = new Rule(this.parent, `${this.stackName}-Rule-${ruleName}`, {
      ruleName: `${this.stackName}-${ruleName}`,
      schedule: Schedule.cron({
        minute: "0",
        hour: "8,20",
      }),
    });

Use Case

For timezones such as Europe/London, currently if I want the schedule to be consistent all year around I need to manually update this field in the console after creating the Rule via CDK.

Proposed Solution

An additional field, timeZone or similar.

const rule = new Rule(this.parent, ${this.stackName}-Rule-${ruleName}, {
ruleName: ${this.stackName}-${ruleName},
schedule: Schedule.cron({
minute: "0",
hour: "8,20",
timeZone: "Europe/London"
}),
});

All timezones in CDK are always UTC.

We wouldn't need AWS events to actually support timezone to support this. It could be achieved by creating multiple rules that trigger depending on the time of year.
An implementation similar to this: https://www.npmjs.com/package/serverless-local-schedule

Supposedly, EventBridge supports timezones, so there just needs to be a way to configure that timezone with CDK: https://aws.amazon.com/blogs/compute/introducing-amazon-eventbridge-scheduler/

Apparently this exists in the aws_cdk.aws_autoscaling.CfnScheduledAction construct. It'd be nice to have it in the aws_cdk.aws_events.Schedule too.

Any updates on this?

[ShaneYen]

Was looking for this functionality as well. any workaround?

[DanielLaberge]

This really ought to be supported. It's a shame and is frustrating when CDK lags behind features offered in the Console.

[LucasSymons]

Time zones and Daylight savings support would be amazing!

[oxc]

Seems like this will be supported in the AWS EventBridge Scheduler (Alpha) construct.

[micheleuno1]

as @oxc said, its actually supported by the alpha Scheduler, after some small troubles, i managed to schedule a Step Function using the correct Time Zone.

This issue has received a significant amount of attention so we are automatically upgrading its priority. A member of the community will see the re-prioritization and provide an update on the issue.

Thanks for the implementation of Timezone in ApplicationAutoscaling. But is that any plan of the implementation for the timezone in EventBridge as the title mention?

I have noticed that timezone support appears to be implemented in the JavaScript version of the AWS CDK, as detailed here: AWS CDK Scheduler library for JavaScript.

However, upon reviewing the Python AWS CDK documentation, particularly the Schedule class, I did not find any references to timezone support for EventBridge cron expressions.

Could you please provide information on whether there are plans to introduce timezone handling in EventBridge for the Python version of the AWS CDK? Additionally, if such functionality is already in development or available, I would greatly appreciate guidance on accessing and utilizing it.

It's incredible to me that the basic functionality to configure a scheduled fargate task using a local time via the Python CDK still appears to be missing. This is a basic feature requirement that AWS just appears to be completely ignoring.
Please could someone from AWS provide an update?

I'm also looking forward for the python CDK implementation of this feature.

Also, looking for this feature

Need this ASAP

[jeff1evesque]

CloudFormation has AWS::Scheduler::Schedule, which supports ScheduleExpressionTimezone. I'm looking for something similar to events.CfnRule. Maybe by the time some of these "priority" tickets get attention, IAC will be obsolete with infrastructure as GPT (IAGPT).

[jeff1evesque]

Lucky me, looks like schedule_expression_timezone is part of scheduler.CfnSchedule. Probably not the same as most of you guys are looking for. But, if you want CFN variation of CDK, it's there, and fits my bill.

Hey I would like to continue activity on this ticket, I think CDK constructs should always have full feature parity with any other interface of the same service.

I am also on Python CDK, so I would like to see it added there as well.
