Which server-side object provides methods for working with dates when writing a script in a privately scoped application?

The `GlideDateTime` object is the primary server-side API for handling date and time values in ServiceNow, offering methods for creating, comparing, and formatting date/time objects, including awareness of time zones and durations. It provides comprehensive functionality for date calculations and conversions.

`current` is a GlideRecord object representing the current record being processed, not a date/time utility.

`GlideRecord` is used to query, insert, update, and delete records in the database, not for date/time manipulation.

`GlideSystem` (gs) provides various utility methods, including some for logging and session information, but `GlideDateTime` is the specific object for date/time operations.
