    Hi there

    Can anyone suggest how to start a service 'tomorrow' at 12:01. Not sure I am using the date formatting correctly as I get errors. Not actually sure I am doing the right thing at all so some code would be nice..

    Thank you in advance,

    Derek.

    Try this ... unsure about the midnight hour (0) have not tested..

    Code:
    Sub Service_Start (StartingIntent As Intent
         ScheduleNextServiceStart(
    0,01)  'schedule service restart ..
         StopService("")
    End Sub

    Sub ScheduleNextServiceStart(Hours As Int, Minutes As Int) 
     
        
    Dim CurrentTime, Today, NextRunTime, HourMinTicks As Long 
     
        
    DateTime.DateFormat = "dd-MM-yyyy"
        HourMinTicks = Hours * 
    DateTime.TicksPerHour + Minutes * DateTime.TicksPerMinute

       
    'calc ticks up to start of today ... 00:00am
       Today = DateTime.DateParse(DateTime.Date(DateTime.Now))
       
    'calc ticks up to current/present time
       CurrentTime = DateTime.Now - Today

       
    If HourMinTicks > CurrentTime Then
           
    'Time has Not passed, schedule For Today
           NextRunTime = Today + HourMinTicks
       
    Else 'Schedule for tomorrow
           NextRunTime = Today + DateTime.TicksPerDay + HourMinTicks
       
    End If
     
       
    StartServiceAt("",NextRunTime,True)
     
       
    Log("NextRunTime:" & NextRunTime & " Date:" & DateTime.Date(NextRunTime) &  "Time:" & DateTime.Time(NextRunTime))
     
    End Sub

    The code above will not work correctly during the two days that the timezone changes (DST effects).

    You can use this code to get the correct time value:
    Code:
    Sub Activity_Create(FirstTime As Boolean)
       
    Log($"Date: $DateTime{TomorrowAt(01)}"$)
    End Sub

    Sub TomorrowAt (Hours As Int, Minutes As Int) As Long
       
    Dim today As Long = DateUtils.SetDateAndTime(DateTime.GetYear(DateTime.Now), _
         
    DateTime.GetMonth(DateTime.Now), _
         
    DateTime.GetDayOfMonth(DateTime.Now), _
         Hours, _
         Minutes, 
    0)
       
    Dim p As Period
       p.Initialize
       p.Days = 
    1
       
    Dim tomorrow As Long = DateUtils.AddPeriod(today, p)
       
    Return tomorrow
    End Sub
