Prevent exception thrown by [DateTime]::ParseExact()

[davehope]

ServiceNow module 4.0.3 uses [DateTime]::ParseExact() in Invoke-ServiceNowRestMethod line 253 + 259. This can result in an exception being thrown, and PowerShell's $error getting populated which it'd be nice to avoid.

An example of where this occurs: DateTimeFormat: dd/MM/yyyy HH:mm:ss SNResult.Property: '2024-05-30 10:40:38'

One approach might be to pass a string[] to ParseExact to make the conversion more likely to succeed. Something like:

                        Try {
                            # Extract the default Date/Time formatting from the local computer's "Culture" settings, and then create the format to use when parsing the date/time from Service-Now
                            $CultureDateTimeFormat = (Get-Culture).DateTimeFormat
                            $DateFormat = $CultureDateTimeFormat.ShortDatePattern
                            $TimeFormat = $CultureDateTimeFormat.LongTimePattern
                            $DateTimeFormat = [string[]]@("$DateFormat $TimeFormat", 'yyyy-MM-dd HH:mm:ss')
                            $SNResult.$Property = [DateTime]::ParseExact($($SNResult.$Property), $DateTimeFormat, [System.Globalization.DateTimeFormatInfo]::InvariantInfo, [System.Globalization.DateTimeStyles]::None)
                        }
                        Catch {
                            # If the local culture and universal formats both fail keep the property as a string (Do nothing)
                            $null = 'Silencing a PSSA alert with this line'
                        }
