UpdatableTimer

README.md

Updatable Timer Sample

Demonstrates a helper class which relies on Workflow.WaitConditionAsync to implement a blocking sleep that can be updated at any moment.

To run, first see README.md for prerequisites. Then, run the following from this directory in a separate terminal to start the worker:

dotnet run worker

Then in another terminal, run the workflow from this directory:

dotnet run workflow

Check the output of the worker window. The expected output is:

Running worker
[14:47:03] info: Temporalio.Workflow:MyWorkflow[0]
    Sleep until: 12/01/2025 01:47:03 +00:00
[14:47:03] info: Temporalio.Workflow:MyWorkflow[0]
    Going to sleep for 23:59:59.9706583

Then run the updater as many times as you want to change timer to 10 seconds from now:

dotnet run update-timer

Check the output of the worker window. The expected output is:

[...]
[14:50:50] info: Temporalio.Workflow:MyWorkflow[0]
    Update wake up time: 11/30/2025 01:51:00 +00:00
[14:50:50] info: Temporalio.Workflow:MyWorkflow[0]
    Going to sleep for 00:00:09.9794955
[14:51:00] info: Temporalio.Workflow:MyWorkflow[0]
    Sleep completed
