Adjust time format

I have run into an issue with a calendar button created in a note not posting the entry correctly in other country because they use different Date Format e.g. for Germany the date is coded as dd.mm.yyyy (instead of mm/dd/yyyy in the US) so there is a swap in month and day. Is there a line of code that will check for the date-format on the machine receiving the button and then set the calender accordingly? below is the code currently using:

Sub Click(Source As Button)

'=======================================================================================

 ' CHANGE THINGS IN THIS SECTION

'=======================================================================================

' this determines which type of calendar entry to make, choose from Appointment, Event, and Reminder

calEntryType = "Appointment"



'this set of variables is for the calendar entry that will be created	

calEntrySubject = "Brown Bag on 'Test'" +Chr(10)+"Presented by Will Atherton"+Chr(10)+"Friday, 7/11/2008, noon-1pm EDT"+Chr(10)+"Hosted from RTP, NC in Bldg 205/DD161"+Chr(10)+"Toll free:  1-888-241-8547"+Chr(10)+"Conference passcode: 324300"+Chr(10)+"Toll:       1-719-884-0812"+Chr(10)+"Tie:        650-3324"

calEntryDetails =  "Charts will be posted to our website http://stgweb.raleigh.ibm.com/MBDev/Technology.html by that morning and audio normally posted shortly after session."+Chr(10)+""+Chr(10)+""+Chr(10)+""+Chr(10)+""

calEntryStartTimeStr = "2008-07-11 12:00:00 PM EDT"

calEntryEndTimeStr = "2008-07-11 01:00:00 PM EDT"



' these are the checkboxes from the options section of a calendar entry

markPrivate = False' Mark Private - do not show other users the details of this calendar entry

remindUser = True		' Notify Me - have Notes remind the user before the calendar entry time



' this set of variables determines whether or not to display the calendar entry to the user after it's added to their calendar

displayCalendarEntry = True	' turns the feature of displaying the saved calendar entry to the user - valid values are True and False



' this set of variables is for the displaying a message to the user if they press the button

displayMessage = True	' turns the message box feature on and off - valid values are True and False

messageToDisplay = "Thank you.   The Brown Bag invitation for 7/11/2008  has been added to your calendar."



' this set of variables deal with sending a reply to the sender of the note when the user presses the button

sendReply = False' turns the reply feature on and off - valid values are True and False

replyRecipient = "Jane Doe/Raleigh/IBM"	' who should get the reply - separate multiple recipients with a comma (,)

replySubject = "Yes, I will attend.."	' subject of the reply message







' this determines which calendar to put the entry into.  If a button is used in email only, it is likely that the calendar entry should be

' created in the email recipient's calendar.  If the button is used in a different context (such as in an application somewhere) this

' may not necessarily be the case since the button will not be in an email note.

' The valid values for this are True and False

buttonUsedInEmailOnly = True
