This method compares the current OracleTimeStamp instance to an object, and returns an integer that represents their relative values.
// C#
public int CompareTo(object obj);
obj
The object being compared to the current OracleTimeStamp instance.
The method returns a number that is:
Less than zero: if the current OracleTimeStamp instance value is less than that of obj.

Greater than zero: if the current OracleTimeStamp instance value is greater than that of obj.
IComparable
ArgumentException - The obj parameter is not of type OracleTimeStamp.
The following rules apply to the behavior of this method.
The comparison must be between OracleTimeStamps. For example, comparing an OracleTimeStamp instance with an OracleBinary instance is not allowed. When an OracleTimeStamp is compared with a different type, an ArgumentException is thrown.
Any OracleTimeStamp that has a value is greater than an OracleTimeStamp that has a null value.
Two OracleTimeStamps that contain a null value are equal.
Overrides Object
This method determines whether or not an object has the same date and time as the current OracleTimeStamp instance.
// C#
public override bool Equals(object obj);
obj
The object being compared to the current OracleTimeStamp instance.
Returns true if the obj is of type OracleTimeStamp and represents the same date and time; otherwise, returns false.
The following rules apply to the behavior of this method.
Any OracleTimeStamp that has a value is greater than an OracleTimeStamp that has a null value.
Two OracleTimeStamps that contain a null value are equal.
Overrides Object
This method returns a hash code for the OracleTimeStamp instance.
// C# public override int GetHashCode();

This method subtracts an OracleTimeStamp value from the current instance and returns an OracleIntervalDS that represents the time difference between the supplied OracleTimeStamp structure and the current instance.
// C#
public OracleIntervalDS GetDaysBetween(OracleTimeStamp value1);
value1
The OracleTimeStamp value being subtracted.
An OracleIntervalDS that represents the interval between two OracleTimeStamp values.
If either the current instance or the parameter has a null value, the returned OracleIntervalDS has a null value.
This method subtracts an OracleTimeStamp value from the current instance and returns an OracleIntervalYM that represents the time difference between the OracleTimeStamp value and the current instance.
// C#
public OracleIntervalYM GetYearsBetween(OracleTimeStamp value1);
value1
The OracleTimeStamp value being subtracted.
An OracleIntervalYM that represents the interval between two OracleTimeStamp values.
If either the current instance or the parameter has a null value, the returned OracleIntervalYM has a null value.
This method converts the current OracleTimeStamp structure to an OracleDate structure.
// C# public OracleDate ToOracleDate();
The returned OracleDate contains the date and time in the current instance.
The precision of the OracleTimeStamp value can be lost during the conversion.
If the value of the OracleTimeStamp has a null value, the value of the returned OracleDate structure has a null value.
This method converts the current OracleTimeStamp structure to an OracleTimeStampLTZ structure.
// C# public OracleTimeStampLTZ ToOracleTimeStampLTZ();
The returned OracleTimeStampLTZ contains date and time in the current instance.

Overrides Object
This method converts the current OracleTimeStamp structure to a string.
// C# public override string ToString();
A string that represents the same date and time as the current OracleTimeStamp structure.
The returned value is a string representation of an OracleTimeStamp in the format specified by the OracleGlobalization.TimeStampFormat property of the thread.
The names and abbreviations used for months and days are in the language specified by the OracleGlobalization's DateLanguage and Calendar properties of the thread. If any of the thread's globalization properties are set to null or an empty string, the client computer's settings are used.
// C#
using System;
using Oracle.DataAccess.Types;
using Oracle.DataAccess.Client;
class ToStringSample
{
static void Main()
{
// Set the nls_timestamp_format for the OracleTimeStamp(string)
// constructor
OracleGlobalization info = OracleGlobalization.GetClientInfo();
info.TimeStampFormat = "DD-MON-YYYY HH:MI:SS.FF AM";
OracleGlobalization.SetThreadInfo(info);
// construct OracleTimeStamp from a string using the format specified.
OracleTimeStamp ts = new OracleTimeStamp("11-NOV-1999 11:02:33.444 AM");
// Set the nls_timestamp_format for the ToString() method
info.TimeStampFormat = "YYYY-MON-DD HH:MI:SS.FF AM";
OracleGlobalization.SetThreadInfo(info);
// Prints "1999-NOV-11 11:02:33.444000000 AM"
Console.WriteLine(ts.ToString());
