PowerShell - Convert Ticks to Time

Question

Converting dates/times into ticks using the PowerShell Get-Date applet is simple. However, how do you do the opposite operation; converting the ticks back into a date and time?

Answer 1

[DateTime]10000000000

Just cast the number into a DateTime . The DateTime single-parameter constructor takes a long as number of ticks.

Answer 2

Note that you can use the Get-Date cmdlet to also do the reverse operation:

PS> Get-Date 634141193308872671

Answer 3

You can also use the New-Object cmdlet:

PS > get-date

PS > (get-date).ticks
634142305097923801

PS > New-Object System.DateTime 634142305097923801
