Just wanted to say thanks. I used Jason’s method since I only needed to subtract days. Worked like a champ and is extremely simple. Nikolas’ solution is very flexible, buta solution I will use it if presented with a more complex requirement.

Thanks,
Dave

Cheers for this, I used a bit of of your code to convert how many Hours, Minutes and seconds there are for so many milliseconds.

$iDuration = new-object system.timespan 0,0,0,0,87633221

[string]$iDuration.Hours+”:”+[string]$iDuration.Minutes+”:”+[string]$iDuration.Seconds

Thanks
James

You can add negative numbers to do subtraction.

PS > $Today = Get-Date
PS > $Today.AddDays(-10)

PS > $Days = 10
PS > $Today.AddDays(-1 * $Days)
