Retrieves the server uptime in milliseconds or a human-readable format.

Get-PodeServerUptime [-Total] [[-Format] <String>] [-ExcludeMilliseconds] [-ProgressAction <ActionPreference>]
 [<CommonParameters>]

The `Get-PodeServerUptime` function calculates the server's uptime since its last start or total uptime since initial load, depending on the `-Total` switch. By default, the uptime is returned in milliseconds. When the `-Format` parameter is used, the uptime can be returned in various human-readable styles:

• `Milliseconds` (default): Raw uptime in milliseconds.
• `Concise`: A short format like "1d 2h 3m".
• `Compact`: A condensed format like "01:10:17:36".
• `Verbose`: A detailed format like "1 day, 2 hours, 3 minutes, 5 seconds, 200 milliseconds". The `-ExcludeMilliseconds` switch allows removal of milliseconds from human-readable output.

$currentUptime = Get-PodeServerUptime
# Output: 123456789 (milliseconds)

$totalUptime = Get-PodeServerUptime -Total
# Output: 987654321 (milliseconds)

$readableUptime = Get-PodeServerUptime -Format Concise
# Output: "1d 10h 17m"

$verboseUptime = Get-PodeServerUptime -Format Verbose
# Output: "1 day, 10 hours, 17 minutes, 36 seconds, 789 milliseconds"

$compactUptime = Get-PodeServerUptime -Format Compact
# Output: "01:10:17:36"

$compactUptimeNoMs = Get-PodeServerUptime -Format Compact -ExcludeMilliseconds
# Output: "01:10:17:36"

Omits milliseconds from the human-readable output when `-Format` is not `Milliseconds`.
