.SYNOPSIS
|
||||
Converts a Timestamp (Epochdate) into Datetime
|
||||
|
||||
.DESCRIPTION
|
||||
Converts a Timestamp (Epochdate) into Datetime
|
||||
|
||||
.PARAMETER TimeStamp
|
||||
Timestamp (Epochdate)
|
||||
|
||||
.PARAMETER Milliseconds
|
||||
Is the given Timestamp (Epochdate) in Miliseconds instead of Seconds?
|
||||
|
||||
.EXAMPLE
|
||||
PS C:\> ConvertFrom-UnixTimeStamp -TimeStamp 1547839380
|
||||
|
||||
Converts a Timestamp (Epochdate) into Datetime
|
||||
|
||||
.EXAMPLE
|
||||
PS C:\> ConvertFrom-UnixTimeStamp -TimeStamp 1547839380712 -Milliseconds
|
||||
|
||||
Converts a Timestamp (Epochdate) into Datetime, given value is in Milliseconds
|
||||
|
||||
.NOTES
|
||||
Added the 'UniFi' (Alias for the switch 'Milliseconds') because the API returns miliseconds instead of seconds

.DESCRIPTION
|

Converts a Datetime into a Unix Timestamp (Epochdate)
|

.PARAMETER Date
|

The Date String that should be converted, default is now (if none is given)
|

.PARAMETER Milliseconds
|

Should the Timestamp (Epochdate) in Miliseconds instead of Seconds?
|

.EXAMPLE
|

PS C:\> ConvertTo-UnixTimeStamp
|

|

Converts the actual time into a Unix Timestamp (Epochdate)
|
||||
|
||||
.EXAMPLE
|
||||
PS C:\> ConvertTo-UnixTimeStamp -Milliseconds
|
||||
|
||||
Converts the actual time into a Unix Timestamp (Epochdate), in milliseconds
|
||||
|
||||
.EXAMPLE
|
||||
PS C:\> ConvertTo-UnixTimeStamp -Date ((Get-Date).AddDays(-1))
|
||||
|
||||
Covert the same time yesterday into a Unix Timestamp (Epochdate)
|

.EXAMPLE
|

PS C:\> ConvertTo-UnixTimeStamp -Date ((Get-Date).AddDays(-1)) -Milliseconds
