TimeString always returns the system time as "HH:mm:ss", which is a 24-hour format. This format is culture-invariant, which means it does not change even if you change the Regional Options in Control Panel.
To get or set the current system date as a String, use the DateString property.
To get the current system date or time in the format of your locale, or in a custom format, supply the Now property to the Format function, specifying either a predefined or user-defined date/time format. The following example demonstrates this.
Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
