Starting with the .NET Framework version 2.0, the return value is a DateTime whose Kind property returns DateTimeKind::Utc.
An alternative to using UtcNow is DateTimeOffset::UtcNow. While the former indicates that a date and time value is Coordinated Universal Time (UTC) by assigning DateTimeKind::Utc to its DateTime::Kind property, the latter assigns the date and time value the UTC time's offset (equal to TimeSpan::Zero).
Windows Mobile for Pocket PC, Windows Mobile for Smartphone, Windows CE Platform Note: In Windows CE, time is specific only to the second. You can get a more precise time span measurement, for example, in milliseconds, by using the TickCount property.
The following example uses the SpecifyKind method to demonstrate how the Kind property influences the ToLocalTime and ToUniversalTime conversion methods.
