The CDF_PARSE_TT2000 function parses a single or an array of input strings into an 8-byte integer (LONG64) value(s) for use as a CDF_TIME_TT2000 type variable. CDF_TIME_TT2000 variables may be encoded into a variety of formats using the CDF_ENCODE_EPOCH function or decomposed into date/time components using CDF_TT2000, /BREAKDOWN_EPOCH function.
Result = CDF_PARSE_TT2000(Epoch_string)
Returns a single value or an array (<= 2D) of 8-byte integer values of the input string(s).
A formatted string that is parsed into a double precision value to be used as a CDF_TIME_TT2000 data type. The format can be one of the predefined formats.
The default format expected by CDF_PARSE_TT2000 is:
yyyy-MM-DDThh:mm:ss.cccuuunnn
where:
|
Date Element |
Represents |
|
YYYY |
the year (A.D.) |
|
MM |
the month number (1-12) |
|
DD |
the day of the month (1-31) |
|
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) |
Note: T is a CDF_EPOCH type 3 placeholder. For more information about CDF_EPOCH values, see “Data Types” in the CDF User’s Guide.
