CDF_PARSE

Scientific Data Formats: Common Data Format

CDF_PARSE_EPOCH

The CDF_PARSE_EPOCH function parses a properly-formatted input string into a double-precision value properly formatted for use as a CDF_EPOCH variable.

Note
CDF_EPOCH variables may be unparsed into a variety of formats using the CDF_ENCODE_EPOCH function.

Syntax

Result = CDF_PARSE_EPOCH(Epoch_string)

Return Value

Returns the double-precision value of the input string properly formatted for use as a CDF_EPOCH variable.

Arguments

Epoch_string

A formatted string that will be parsed into a double precision value suitable to be used as a CDF_EPOCH value. The format of the date string is:

DD-Mon-YYYY hh:mm:ss.ccc

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`)
`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)
