Table 148. Parameters
Name	Type	Description
dateTime	Object	The date and time to use. This parameter may be one of several types. A string in the UTC time zone and the internal format of yyyy-MM-dd HH:mm:ss: Sets the value of the object to the specified date and time. Using the method this way is equivalent to instantiating a new GlideDateTime object using the GlideDateTime(value) constructor. If the date and time format used doesn’t match the internal format, the method attempts to set the date and time using other available formats. Resolving the date and time this way can lead to inaccurate data due to ambiguity in the day and month values. When using a non-standard date and time format, use setValueUTC(dateTime, format) instead. A GlideDateTime object: Sets the value of the object to the date and time stored by the GlideDateTime passed in the parameter. Using the method this way is equivalent to instantiating a new GlideDateTime object using the GlideDateTime(g) constructor. A Java Date object: Sets the value of the object using the value stored by the Java Date object. Using the method this way is equivalent to passing the value returned by the Java Date object getTime() to the GlideDateTime setNumericValue() method. This method doesn’t accept JavaScript Date objects. A JavaScript Number: Sets the value of the object using the Number value as milliseconds past January 1, 1970 00:00:00 UTC. Using the method this way is equivalent to the setNumericValue(milliseconds) method. A Java Integer or Long: Sets the value of the object using the Integer or Long value as milliseconds past January 1, 1970 00:00:00 UTC. Using the method this way is equivalent to the setNumericValue(milliseconds) method.

Table 149. Returns

GlideDateTime - setValueUTC(String dateTime, String format)

Sets a date and time value using the UTC time zone and the specified date and time format.

This method throws a runtime exception if the date and time format used in the dateTime parameter does not match the format parameter. You can retrieve the error message by calling getErrorMsg() on the GlideDateTime object after the exception is caught.
