All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<java.util.Date>

public class OS_TimeStamp
extends java.util.Date

This class is useable in C. In Java it should be derived from Date because it is used at example in SimpleDateFormat.format(...) as argument.

Version, history and license

• 2012-04-05 Hartmut new: os_getSeconds(): seconds are able to process with a 32-bit integer. They are supported in most of operation systems. It is the originally unix concept for the timestamp. It should be available if measurements of seconds are enough and proper to use. In Java it is the milliseconds from 1970 divide by 1000, converted to (int).
• 2009-00-00 Hartmut: Created as opposite to CRuntimeJavalike/OSAL/os_time.h Intension: Java has some good definitions of a operation system interface. In C it isn't well in this form. The CRuntimeJavalike/OSAL is an approach for an Operation System Adaption Layer in C. This class is the opposite in Java for Java2C.

Method Detail

os_getDateTime

public static OS_TimeStamp os_getDateTime()

Returns an instance with the current system time. In C the instance is returned by value. Therefore no allocation is done. In Java a new instance is created.

set

public OS_TimeStamp set(OS_TimeStamp src)

Sets this instance to the timestamp given in src.

Parameters:

src - Any source.

Returns:

this

os_delayThread

public static boolean os_delayThread(int millisec)

os_getSeconds

public static int os_getSeconds()
