I work on a team that has members across different time zones. It is important to ensure that I schedule meetings such that team members do not have to either stay late or wake up early. Being a command line person, I quickly wrote this PowerShell script to help me determine the time differences.

)
if (!$Target)
{
# Get the local time as the target
$Target = Get-Date
}
$tzObject = [System.Collections.Arraylist]::new()
$tzObject.Add(
[PSCustomObject]@{
'Timezone' = 'Local'
'Time' = $Target
'DifferenceInHours' = 0
}
) | Out-Null
foreach ($tz in $Timezone)
{
# Get the timezone difference
$localTz = [System.TimeZoneInfo]::Local
$remoteTz = [System.TimeZoneInfo]::FindSystemTimeZoneById($tz)
$tzDifference = [float]($remoteTz.BaseUtcOffset.TotalHours - $localTz.BaseUtcOffset.TotalHours)
$remoteTime = [System.TimeZoneInfo]::ConvertTime($Target, $localTz, $remoteTz)
$tzObject.Add(
[PSCustomObject]@{
'Timezone' = $tz
'Time' = $remoteTime
'DifferenceInHours' = $tzDifference
}
) | Out-Null
}
return $tzObject
|
This one is simple to use.

When you do not specify any target time to convert, this script uses the current local time and converts to the time zones specified at the command line.

You can specify a target time to convert using the -Target parameter. You can specify a future target time to schedule the meeting using this parameter.
I hope you find this useful as well.
