Bicep : The provided time T09:00:28Z does not follow the ISO 8601 standard.

Error:

New-AzResourceGroupDeployment: 10:18:37 - The deployment 'avd' failed with error(s). Showing 1 out of 1 error(s).
Status Message: The provided time T09:00:28Z does not follow the ISO 8601 standard. (Code:InvalidIso8601Time)

Code:

resource shutdownSchedule_1 'Microsoft.DevTestLab/schedules@2018-09-15' = {

  name: 'LabVmsShutdown'

  location: param_location

  properties: {

    status: 'Enabled'

    taskType: 'LabVmsShutdownTask'

    dailyRecurrence: {

      time: 'T09:00:28Z'

    }

    timeZoneId: 'CET'

    targetResourceId: p_vm1_id

  }

}

How should the time be formatted ?

[#2]

 The time should be formatted according to the ISO 8601 standard, which requires the time to be in the format of "hh:mm:ss" with an optional fractional component for seconds, followed by the time zone offset in the format of "+/-hh:mm" or "Z" for UTC.

In this case, the provided time "T09:00:28Z" is missing the fractional component for seconds, which is required by the ISO 8601 standard. To fix the error, you can add the fractional component for seconds, such as "T09:00:28.000Z".

The corrected code for the dailyRecurrence property would be:

 dailyRecurrence: {
time: 'T09:00:28.000Z'
}

Thanks for your reply.

I just tested and receive the following error message:
I Status Message: The provided time T09:00:28.000Z does not follow the ISO 8601 standard. (Code:InvalidIso8601Time)

I copy pasted the format from your reply.

@Wim_Kestens 

Error message is related to the format of the timestamp.

YYYY-MM-DDThh:mm:ss.sssZ
Where:

YYYY: Year
MM: Month (01-12)
DD: Day (01-31)
T: Time separator
hh: Hour (00-23)
mm: Minute (00-59)
ss: Second (00-59)
sss: Millisecond (000-999)
Z: Timezone offset (e.g. +00:00)
So, for example, the timestamp for March 1st, 2023 at 9:00:28 AM UTC would be:

2023-03-01T09:00:28.000Z

To use this format when providing timestamps to any commands or APIs that require it.

Herewith my code that works.

Thanks for your assistance.
