All Implemented Interfaces:: CDFConstants

public class Epoch16
extends java.lang.Object
implements CDFConstants

This class contains the handy utility routines (methods) called by the CDF applications to handle epoch data of CDF's CDF_EPOCH16 data type.

Version:

1.0 Example:

 
 // Get the time, down to picoseconds, for Aug 5, 1990 at 5:0:0.0.0.0
 double[] epoch16 = new double[2];
 double ep = Epoch16.compute(1990, 8, 5, 5, 0, 0, 0, 0, 0, 0, epoch16);
 //Get the year, month, day, hour, minutes, seconds, milliseconds,
 //    microseconds, nanaseconds and picoseconds for epoch16
 long[] times = Epoch16.breakdown(epoch16);
 for (int i=0;i<times.length;i++)
     System.out.print(times[i]+" ");
 System.out.println();
 // Printout the epoch in various formats
 System.out.println(Epoch16.encode(epoch16));
 System.out.println(Epoch16.encode1(epoch16));
 System.out.println(Epoch16.encode2(epoch16));
 System.out.println(Epoch16.encode3(epoch16));
 System.out.println(Epoch16.encode4(epoch16));
 // Print out the date using format
 String format = "<month> <dom.02>, <year> at <hour>:<min>";
 System.out.println(Epoch16.encodex(epoch16,format));

  - Epoch16toUnixTime
```
public static double Epoch16toUnixTime(java.lang.Object epoch)
```
    Converts an EPOCH16 value to a unix time of a double value (seconds from 1970-01-01 00:00:00 UTC). The unix time will have a time resolution of microseconds at its fraction part. Note: As EPOCH16 have a higher time resolution than the unix time. The conversion might not precisely preserve the microseconds due to the floating point presentation.

```
    Converts a unix time of a double value (seconds from 1970-01-01 00:00:00 UTC) to an EPOCH16 value. The unix time can have a time resolution in microseconds at its fraction part. Note: As EPOCH16 have a higher time resolution than the unix time. The conversion might not precisely preserve the microseconds due to the floating point presentation.
    
    Parameters:
    
    unixTime - the unix time value
    
    Returns:
    
    An EPOCH16 value (2-double)
