CDF_ENCODE_EPOCH16

Scientific Data Formats: Common Data Format

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:


Value	Date Format
0	`DD-Mon-YYYY hh:mm:ss.ccc.uuu.nnn.ppp`(This is the default)
1	`YYYYMMDD.ttttttttttttttt`
2	`YYYYMMDDss`
3	`YYYY-MM-DDThh:mm:ss.ccc.uuu.nnn.pppZ`(The characters `T` and `Z` are the CDF_EPOCH16 type 3 place holders)

where:


Date Element	Represents
`DD`	the day of the month (1-31)
`Mon`	the abbreviated month name: (`Jan`, `Feb`, `Mar`, `Apr`, `May`, `Jun`, `Jul`, `Aug`, `Sep`, `Oct`, `Nov`, or `Dec`)
`MM`	the month number (1-12)
`YYYY`	the year (A.D.)
`hh`	the hour (0-23)
`mm`	the minute (0-59)
`ss`	the second (0-59)
`ccc`	the millisecond (0-999)
`uuu`	the microsecond (0-999)
`nnn`	the nanosecond (0-999)
`ppp`	the picosecond (0-999)
`ttttttttttttttt`	the fraction of the day (e.g. 500000000000000 is noon).
