Another time issue with Book A Room App

Hello 
Yes, I am an absolute beginner in using PowerApps, so please don't blame me for my question - please 🙂

Here we go:
The Book A Room - App shows available time slots in a 30min grid. I changed that in 5min slots by adjusting the initial settings to:

 

[..]
ClearCollect(Times;{Text: "07:00";Minutes: 420};
{Text: "07:05";Minutes: 425};
[..]

I also changed the settings where the MOD is calculated to

 

Set(DateSelected; Today());;
Set(DateTimeRoomChange; true);;
If(
Mod(Minute(Now()); 5) <= 2;
Set(StartDateTime; DateAdd(Now(); -Mod(Minute(Now()); 5); Minutes));;
Set(EndDateTime; DateAdd(StartDateTime; 5; Minutes));
Mod(Minute(Now()); 5) >= 3;
Set(StartDateTime; DateAdd(Now(); -Mod(Minute(Now()); 5) + 5; Minutes));;
Set(EndDateTime; DateAdd(StartDateTime; 5; Minutes));
Set(StartDateTime; Now());;
Set(EndDateTime; DateAdd(Now(); -Mod(Minute(Now()); 5) + 5; Minutes))
);;

 

In my understanding this calculates times by checking if the MOD of 'Actual Minutes' / 5 is equal less 2 or equal more than 3. Afterwards adjusting the start time in parts of 5min. Works all well, as far as I can see.

But when it comes to select a start time, the query always sends a 'No rooms available' back, when the start time is unequal to a full hour or half hour (like 09:25). When the start time is equal to a full or half hour (like 09:00 or 09:30), available rooms are shown properly.

I really cannot find any other variables or settings, where I can adjust that 30min grid to a 5min grid.

Any help appreciated 🙂

Is there any solution? Got the same problem.

Still no answer.. 😕
This is somewhat sad, because my school could use this app, indeed...

Ok, I'll post my adjusted script. Maybe someome can find any issues with that...

App on Start:

ClearCollect(Times; 
{Text: "00:00"; Minutes: 0};
{Text: "00:05"; Minutes: 5};
{Text: "00:10"; Minutes: 10};
{Text: "00:15"; Minutes: 15};
{Text: "00:20"; Minutes: 20};

..and so on

Landing-Screen (Button NoMeeting) - these are my adjustments to achieve a 5min timetable instead of the (working) 30mins:

Set(DateTimeRoomChange; true);;
If(Mod(Minute(Now()); 5) <= 2; 
    Set(StartDateTime; DateAdd(Now(); -Mod(Minute(Now()); 5); Minutes));;
    Set(EndDateTime; DateAdd(StartDateTime; 5; Minutes));
   Mod(Minute(Now()); 5) >= 3;
    Set(StartDateTime; DateAdd(Now(); -Mod(Minute(Now()); 5) + 5; Minutes));;
    Set(EndDateTime; DateAdd(StartDateTime; 5; Minutes));
   Set(StartDateTime; Now());;
   Set(EndDateTime; DateAdd(Now(); -Mod(Minute(Now()); 5) + 10; Minutes))
);;

Set(StartDateTimeUTC; Text(DateAdd(StartDateTime; TimeZoneOffset(); Minutes); "[$-en]yyyy-mm-ddThh:mm") & ":00.000Z");;
Set(EndDateTimeUTC; Text(DateAdd(EndDateTime; TimeZoneOffset(); Minutes); "[$-en]yyyy-mm-ddThh:mm") & ":00.000Z");;

Set(BookForMeeting; false);;

If(NoRoomsList;
    Navigate(RoomSelectScreen; Cover);
    
    Navigate(RoomListSelectScreen; Cover)
)


RoomSelect-Screen (OnVisible):

Set(IsPrevRoomSelect; false);;
If(DateTimeRoomChange;
    Set(AvailableRoomsCounter; 1);;
    UpdateContext({ShowLoading: true});;
    Set(RoomsLeft; Blank());;
    If(!NoRoomsList;
        ClearCollect(AllRooms; Office365.GetRoomsInRoomList(RoomsListsGallery.Selected.Address).value)
    );;
    Set(DateTimeRoomChange; false);;
   /* 
    If(CountRows(AllRooms) > 20,
        Set(AllRoomsConnector; Concat(FirstN(AllRooms, 20), Address & ";"));
        If(CountRows(AllRooms) > 40, 
            Set(AllRoomsConnector1, Concat(LastN(FirstN(AllRooms, 40), 20), Address & ";"))
        ),
        Set(AllRoomsConnector, Concat(AllRooms, Address & ";"))
    );
    
    Office365.FindMeetingTimesV2({RequiredAttendees: AllRoomsConnector, IsOrganizerOptional: true, Start: Now(), End: DateAdd(Now(),1,Hours), MeetingDuration: 30, MinimumAttendeePercentage: "1", ActivityDomain: "Unrestricted"}));
    */
    
    Set(AllRoomsConnector; Concat(FirstN(AllRooms; 20); Address & ";"));;

    
    Concurrent(
        ClearCollect(AvailableRooms; Office365.FindMeetingTimes({RequiredAttendees: AllRoomsConnector; IsOrganizerOptional: true; 
            Start: StartDateTimeUTC; End: EndDateTimeUTC; MeetingDuration: DateDiff(StartDateTime; EndDateTime; Minutes);
            MinimumAttendeePercentage: "1"; ActivityDomain: "Unrestricted"}));

        If(CountRows(AllRooms) > 20;
            If(CountRows(AllRooms) > 40;
                Set(AllRoomsConnector1; Concat(LastN(FirstN(AllRooms; 40); 20); Address & ";"));
                Set(AllRoomsConnector1; Concat(LastN(AllRooms; CountRows(AllRooms) - 20); Address & ";"))
            );;
            ClearCollect(AvailableRooms1; Office365.FindMeetingTimes({RequiredAttendees: AllRoomsConnector1; IsOrganizerOptional: true; 
                Start: StartDateTimeUTC; End: EndDateTimeUTC; MeetingDuration: DateDiff(StartDateTime; EndDateTime; Minutes);
                MinimumAttendeePercentage: "1"; ActivityDomain: "Unrestricted"})
            );
        Clear(AvailableRooms1)
        )
        
    );;
    If(CountRows(AllRooms) > 20;
        Collect(AvailableRooms; AvailableRooms1)
    );;
    ClearCollect(AvailableRoomsSorted; SortByColumns(First(AvailableRooms).MeetingTimeSuggestions; "Confidence"; Descending); If(CountRows(AllRooms) > 20; SortByColumns(Last(AvailableRooms).MeetingTimeSuggestions; "Confidence"; Descending)));;

    ClearCollect(AvailableRoomsConcat; Concat(Filter(First(AvailableRoomsSorted).AttendeeAvailability; Availability = "Free"); 
        Attendee.EmailAddress.Address; ","); If(CountRows(AllRooms) > 20; Concat(Filter(Last(AvailableRoomsSorted).AttendeeAvailability; Availability = "Free"); 
        Attendee.EmailAddress.Address; ",")));;

    ClearCollect(AvailableRoomEmails; Split(First(AvailableRoomsConcat).Value; ","); If(CountRows(AllRooms) > 20; Split(Last(AvailableRoomsConcat).Value; ",")));;

    ClearCollect(AvailableRoomEmailName; AddColumns(RenameColumns(AvailableRoomEmails; "Result"; "Email"); "Name"; 
        LookUp(AllRooms; Email = Address).Name));;
    UpdateContext({ShowLoading: false});;
    Set(RoomsLeft; CountRows(AllRooms) - 40 * AvailableRoomsCounter)
);;
Clear(AvailableRooms);;
Clear(AvailableRooms1)

 

the problem must be located somewhere here; because if I set start times unequal to xx:00 or xx:30 no rooms are returned..

Ok. it seems I#'ve got a solution; finally 🙂

 

The problem seems to be somewhere in the date/time format that is created in the app.
For me (location Germany) the whole thing started to work at the moment I introduced a second DateTimeUTC; like:

Set(StartDateTimeUTC; Text(DateAdd(StartDateTime; TimeZoneOffset(); Minutes); "[$-en]dd-mm-yyyyThh:mm:") & "00.000Z");;
Set(EndDateTimeUTC; Text(DateAdd(EndDateTime; TimeZoneOffset(); Minutes); "[$-en]dd-mm-yyyyThh:mm:") & "00.000Z");;
Set(StartDateTimeUTC2; Text(DateAdd(StartDateTime; TimeZoneOffset(); Minutes); "[$-en]yyyy-mm-ddThh:mm:") & "00.000Z");;
Set(EndDateTimeUTC2; Text(DateAdd(EndDateTime; TimeZoneOffset(); Minutes); "[$-en]yyyy-mm-ddThh:mm:") & "00.000Z");;

 

As you can see StartDateTimeUTC follows German rules to show a date; which is like Day Month - Year

The second StartDateTimeUTC2 follows a rather logical rule, which is Year - Month - Day

 

So what have I done?
1. I exchanged every row in the BookARoom-App where these two variables are set or changed.

2. Next I changed the 'On Visible' in the ConfirmationScreen in that way, that every StartDateTimeUTC was changed into StartDateTimeUTC2
Now I see all rooms which are available in ticks of 5min; regardless of the starting time - working

Now I can book the room with the disered span of time (min 5min) - working

 

I would lie if I told you I understand the whole thing - I don't *g* but it works... Yeah 🙂

(This is just a short description what I did to make this app work for me. If you are interested in the details, please send me a notification)

Hey kannst du vielleicht die ganze App hier anfügen? Ich denke es betrifft viele Stellen im Code oder? Danke und schön, dass du das Problem gelöst hast.

Ich habe hier meine Version der Raumbuchungs-App angefügt.
Zahlreiche Anpassung im optischen Design

Viele Codeschnipsel geändert; darunter insbesondere:
- Änderung der Zeit-Ticks von 30min auf 5min-Intervalle
- Hinzufügen von Variablen DateTimeStart/EndUTZ2, um Buchung durchzuführen
- Änderung des Timecodes, um Raumbuchungen/Outlook abzufragen; von yyyy-mm-ddThh:mm auf dd-mm-yyyyThh:mm

Bei Fragen bitte kurze Nachricht
Hinweis: Ich habe die Befürchtung, dass die Zeitabfrage immer noch nicht korrekt funktioniert
