CDF_PARSE_EPOCH16

CDF_PARSE_EPOCH16

The CDF_PARSE_EPOCH16 function parses a properly-formatted input string into a double-complex value properly formatted for use as a CDF_EPOCH16 variable.

Note: CDF_EPOCH16 variables may be unparsed into a variety of formats using the CDF_ENCODE_EPOCH16 or CDF_EPOCH16 functions.

Example


test_string = '04-Dec-2005 20:19:18.176.214.648.000' 
test_epoch = CDF_PARSE_EPOCH16(test_string) 
CDF_EPOCH16, test_epoch, year, month, day, hour, min, sec, $
   milli, micro, nano, pico, /BREAKDOWN_EPOCH
HELP, test_string, test_epoch 
PRINT, CDF_ENCODE_EPOCH16(test_epoch)
PRINT, year, month, day, hour, min, sec, milli, micro, nano, pico
 

IDL Prints:

TEST_STRING     STRING    = '04-Dec-2005 20:19:18.176.214.648.000'
TEST_EPOCH      DCOMPLEX  = (   6.3300947e+10,   1.7621465e+11)

Syntax


Result = CDF_PARSE_EPOCH16(Epoch_string)

Return Value


Returns the double-precision complex value of the input string properly formatted for use as a CDF_EPOCH16 variable.

Arguments


Epoch_string

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

DD-Mon-YYYY hh:mm:ss.ccc.uuu.nnn.ppp

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

hh

the hour (0-23)

mm

the minute (0-59)

ss

the second (0-59)

ccc

the millisecond (0-999)

uuu
