Increment hours by 30 minutes 20 times in Powershell-CodePudding

I have to create multiple job in my app. These jobs should be separated by 30 minutes apart starting at 17:00. My dilemma how to get 20 times in hour and minutes ( HH:MM) format starting at 17:00 ?? Onces i have those times , i can loop all jobs 30 minutes apart. Thank you

So far i have tried

$ts = New-TimeSpan -Hours 17 -Minutes 00

But adding minutes to $ts not working

PS F:\> $ts.AddMinutes(30)
Method invocation failed because [System.TimeSpan] does not contain a method named 'addminutes'.
At line:1 char:1
  $ts.AddMinutes(30)

You can simply add a new timespan:

$newts = $ts   (New-TimeSpan -Minutes 30)

Paolo's helpful answer shows how to add a timespan to an existing timespan, where the operation translates to the [timespan] type's .Add() method.

By contrast, it is the [datetime] / [datetimeoffset] types that have an .AddMinutes() .AddMinutes() method.

Therefore, you could do the following:

# Get today's date at 17:00 hours
$start = Get-Date -Hour 17 -Minute 0 -Second 0 -MilliSecond 0
# Loop 20 times and add 30 minutes each, and format as "HH:mm"
0..19 | ForEach-Object { $start.AddMinutes($_ * 30).ToString('HH:mm') }

Output:

You can add a string that will automatically convert to type [timespan], since the left argument is [timespan]:

$ts = [timespan]'17:30'
$ts  = '0:30'
