Function: parse-ixf-timestamp DATA POS LENGTH

Read an IXF timestamp string.

From the docs:

Each time stamp is a character string of the form yyyy-mm-dd-hh.mm.ss.nnnnnn (year month day hour minutes seconds fractional seconds).

Starting with Version 9.7, the timestamp precision is contained in the IXFCLENG field of the column descriptor record, and cannot exceed 12. before Version 9.7, IXFCLENG is not used, and should contain blanks.

Valid characters within TIMESTAMP are invariant in all PC ASCII code pages; therefore, IXFCSBCP and IXFCDBCP are not significant, and should be zero.
