How to Convert Utc Datetime String In Powershell?

In PowerShell, you can convert a UTC datetime string using the [datetime]::ParseExact method. This method allows you to specify the format of the datetime string so that PowerShell can accurately convert it to a datetime object. The format string for a UTC datetime string typically looks like "yyyy-MM-ddThh:mm:ssZ".

Here's an example of how you can convert a UTC datetime string in PowerShell:

1
2

$utcDateString = "2021-10-15T14:30:00Z"
$utcDateTime = [datetime]::ParseExact($utcDateString, "yyyy-MM-ddTHH:mm:ssZ", [System.Globalization.CultureInfo]::InvariantCulture)

After running this code, the variable $utcDateTime will contain a datetime object that represents the UTC datetime specified in the $utcDateString variable. You can then use this datetime object for further processing or conversion as needed.

How to convert utc datetime string in powershell using custom functions?

To convert a UTC datetime string in Powershell using custom functions, you can create a function that takes the UTC datetime string as input and converts it to the local timezone. Here's an example of how you can achieve this:

function ConvertFromUtcToLocal {
    param (
        [string]$utcDateTime
    )

    $utcTime = [datetime]::ParseExact($utcDateTime, "yyyy-MM-ddTHH:mm:ssZ", [System.Globalization.CultureInfo]::InvariantCulture)
    $localTime = $utcTime.ToLocalTime()

    return $localTime.ToString("yyyy-MM-dd HH:mm:ss")
}

# Test the function
$utcDateTime = "2022-01-01T12:00:00Z"
$localDateTime = ConvertFromUtcToLocal $utcDateTime
Write-Output "UTC datetime: $utcDateTime"
Write-Output "Local datetime: $localDateTime"

In this example, the ConvertFromUtcToLocal function takes a UTC datetime string in the format "yyyy-MM-ddTHH:mm:ssZ" and converts it to the local timezone. The function uses the ParseExact method to parse the UTC datetime string and then calls the ToLocalTime method to convert it to the local timezone. Finally, the function returns the local datetime string in the format "yyyy-MM-dd HH:mm:ss".

You can test the function by passing a UTC datetime string to it and then printing the original UTC datetime string and the converted local datetime string.

How to convert utc datetime string in powershell to milliseconds?

You can convert a UTC datetime string to milliseconds in PowerShell by using the following code:

1
2
3

$utcDateString = "2021-06-13T15:30:00Z"
$utcDateTime = [datetime]::ParseExact($utcDateString, "yyyy-MM-ddTHH:mm:ssZ", [System.Globalization.CultureInfo]::InvariantCulture)
$utcMilliseconds = ([int64]$utcDateTime.ToUniversalTime().Subtract([datetime]'1970-01-01 00:00:00').TotalMilliseconds)

This code first parses the UTC datetime string to a datetime object using ParseExact method and then converts it to milliseconds by subtracting it from the Unix Epoch time (1970-01-01 00:00:00) and getting the total milliseconds.

How to convert utc datetime string in powershell to hours?

You can convert a UTC datetime string to hours in PowerShell by using the following code:

1
2
3
4

$utcDateTimeString = "2022-01-02T15:30:00Z"
$utcDateTime = [datetime]::ParseExact($utcDateTimeString, "yyyy-MM-ddTHH:mm:ssZ", $null)
$hours = $utcDateTime.ToLocalTime().Hour
Write-Output $hours

In this code snippet:

1. Replace the $utcDateTimeString with your UTC datetime string.
2. Parse the UTC datetime string using [datetime]::ParseExact() method with the format "yyyy-MM-ddTHH:mm:ssZ".
3. Use the ToLocalTime() method to convert the UTC datetime to local time.
4. Get the hour component of the converted datetime using the Hour property.
5. Output the hours value using Write-Output.

This will give you the hour component of the converted datetime in local time.
