The CDF_ENCODE_EPOCH16 function encodes a CDF_EPOCH16 value into the standard date and time character string.
Result = CDF_ENCODE_EPOCH16(Epoch16 [, EPOCH={0 | 1 | 2 | 3}] )
Returns the string representation of the given CDF_EPOCH16 value.
The double-precision CDF_EPOCH16 value to be encoded.
Note: The CDF_EPOCH16 value can be obtained by calling CDF_EPOCH16 with the COMPUTE keyword, or by calling CDF_PARSE_EPOCH16.
Set this keyword equal to one of the following integer values, specifying the epoch mode to use for output of the epoch date string:
