What is requestedPublishingInterval when creating a subscription ?

[argiraud]

Hi,
To create a subscription we need to have an attribute requestedPublishingInterval with the method createSubscription but I don't understand which double value I should put.
Someone can help me to figure what this value is about pls

Thank you

Here's an excerpt from Part 4 of the OPC UA spec, which you should read to fully understand how subscriptions work:

Subscriptions have a publishing interval. The publishing interval of a Subscription defines the cyclic rate at which the Subscription executes. Each time it executes, it attempts to send a NotificationMessage to the Client. NotificationMessages contain Notifications that have not yet been reported to Client.
