Microsoft Task Scheduler's: Schtasks.exe unable to register new task in Arabic OS (locale)

Question

I created a task in MS Task Scheduler app using simple xml command approach:

SCHTASKS /CREATE /SC DAILY /TN "TEST" /XML "C:\TEST.xml"

When I try to register the task in an Arabic regional OS setting/machine the task registration fails.

• Failed command_prompt (image):

XML (task):

<Task version="1.2" xmlns="...">
  <RegistrationInfo>
    <Date>1441-04-07T11:33:39</Date> 
    <URI>TEST</URI>  
  </RegistrationInfo>
  <Triggers>
    <TimeTrigger>
      <StartBoundary>1441-04-07T11:33:39-08:00</StartBoundary>
       ..

But, if I edit the date in this Xml to our default 2019 (en-US based calendar) instead of that Arabic (Hijri calendar) year 1441, the task registers successfully:

• Success command_prompt (image):

<Task version="1.2" xmlns="...">
      <RegistrationInfo>
        <Date>2019-04-12T11:33:39</Date>
        <URI>TEST</URI>    
      </RegistrationInfo>
      <Triggers>
        <TimeTrigger>
          <StartBoundary>2019-04-12T11:33:39-08:00</StartBoundary>
           ..

I am using this command from a Wpf UI application so I cannot put non-localized date format in it. Please let me know how to register this task in that localized machine! Thanks a lot.
