<# .SYNOPSIS Compare-IcingaUnixTimeWithDateTime compares a DateTime-Object with the current DateTime and returns the offset between these values as Integer .DESCRIPTION Compare-IcingaUnixTimeWithDateTime compares a DateTime-Object with the current DateTime and returns the offset between these values as Integer .PARAMETER DateTime DateTime object you want to compare with the Universal Time .INPUTS System.DateTime .OUTPUTS System.Int64 #> function Compare-IcingaUnixTimeWithDateTime() { param ( [datetime]$DateTime ); # This is when the computer starts counting time $UnixEpochStart = (New-Object DateTime 1970, 1, 1, 0, 0, 0, ([DateTimeKind]::Utc)); # We convert the creation and current time to seconds $CreationTime = [long][System.Math]::Floor((($DateTime.ToUniversalTime() - $UnixEpochStart).Ticks / [timespan]::TicksPerSecond)); $CurrentTime = Get-IcingaUnixTime; # To find out, from the snapshot creation time to the current time, how many seconds are, # you have to subtract from the (Current Time in s) the (Creation Time in s) return ($CurrentTime - $CreationTime); } |
