public int CompareTo(
	AFTimeZone obj
)

Public Function CompareTo ( 
	obj As AFTimeZone
) As Integer

public:
virtual int CompareTo(
	AFTimeZone^ obj
) sealed

abstract CompareTo : 
        obj : AFTimeZone -> int 
override CompareTo : 
        obj : AFTimeZone -> int

Parameters

obj: Type: OSIsoft.AF.TimeAFTimeZone
The object to be compared.

Return Value

Type: Int32

A 32-bit signed integer that indicates the relative order of the comparands. The return value has these meanings:

Value	Meaning
Less than zero	This instance is less than obj.
Zero	This instance is equal to obj.
Greater than zero	This instance is greater than obj.

Implements

IComparableTCompareTo(T)

Exceptions

Exception	Condition
ArgumentException	The obj parameter is not the same type as this instance.

Remarks

By definition, any object compares greater than and two null references compare equal to each other.

This method uses the Time Zone's bias from Coordinated Universal Time (UTC) to perform the comparison operation. If the bias is equal, a secondary comparison is done on the Name property.
