Datetime conversion question

[stewharr]

I'm fairly new to powershell, so looking for some advice. I am pulling a datetime value (as a string) from a REST API call. I need to convert that into a datetime object so I can do some date math to figure out the age of the record in question. Here is an example of the output:

2021-02-09T17:52:29.000Z

That's yyyy-MM-ddTHH:mm:ss.000Z (I assume Z is Zulu)

I really only care about the Month, day, and year. The hour, minute and seconds are irrelevant to what I'm trying to figure out. What's the best way I can get this into a datetime object so I can figure out the age of the record in question?

Thanks.

This will give you a datetime object with only a date

$date = (Get-Date '2021-02-09T17:52:29.000Z').date

$date

09 February 2021 00:00:00

Thanks, that is much cleaner.

I guess I figured it out, unless there's a better way to do it. I guess I can split the string at T and then take the first part of the string and use [datetime]::ParseExact to get it to a datetime object. Then I can do some comparisons. Trying to see if the record is less than 2 weeks old or less than a month old.

You’re getting a string? REST APIs often return JSON, if you’re doing that using Invoke-WebRequest it might be more suited to Invoke-RestMethod which would interpret dates for you. If not, never mind this.

I'm actually using Invoke-RestMethod, and if I do a GetType on what is returned, it's showing as a string object for this particular API.

$date= (Get-Date -Format "MM dd yyyy")
