Timezone in ELSA 3.0

[Manali-23]

I am using ELSA 3.0. I am looking for setting a timezone in ELSA. But not able to find that option.
From one of the old posts of @sfmskywalker, you mentioned that the timezone feature has been added to ELSA 3.0.
Can you please tell me the steps? where I will be able to set that

Elsa 3 does't have timezone implemented yet, so it's good that you created this issue discussion 👍🏻
I will create an issue for it.

Got it. Thank you for confirming @sfmskywalker

any updates on this. would like to have timezone injected in (for SystemClock) especially for Cron expressions with specific times.

Timezones have been implemented
you can inject
Elsa.Studio.Localization.Time.ITimeZoneProvider
with a timezone provider like:
Elsa.Studio.Localization.Time.Providers.LocalTimeZoneProvider
(local time)
something like:
builder.Services.AddScoped<ITimeZoneProvider, LocalTimeZoneProvider>();

Thank you, I will give a try

For runtime scheduling, Elsa currently evaluates cron expressions in UTC; there is no built-in per-workflow or host time-zone setting for SystemClock/the scheduling parser.

The current implementation makes this explicit:

• Elsa.Common.Services.SystemClock exposes DateTimeOffset.UtcNow.
• Elsa.Scheduling.Services.CronosCronParser.GetNextOccurrence calls Cronos with TimeZoneInfo.Utc.
• Elsa.Common.RecurringTasks.CronSchedule also calculates its next occurrence from the UTC system clock.

So the ITimeZoneProvider / LocalTimeZoneProvider registrations mentioned above are for Elsa Studio's display formatting; they do not change server-side cron evaluation.

For a schedule that must run at a local civil time (and follow daylight-saving rules), calculate the required UTC schedule in the host/application layer, or use a scheduler/provider that explicitly supports the desired time zone. There is not currently an Elsa scheduling configuration switch that changes the parser to an arbitrary TimeZoneInfo.
