Appendix D. DTS Extended BNF
This appendix defines the Distributed Time Service (DTS) syntax in extended Backus
Naur Format (BNF) notation.
The BNF for DTS time conversion has four parts: year, day, tdf, and inaccuracy. For any
part whose value is not explicitly expressed, the conversion default value is taken as that
of the current day. The BNF for the DTS time conversion is as follows:
dts_time : year_part day_part tdf_part inacc_part
| year_part day_part tdf_part
| year_part day_part
| year_part day_part inacc_part
| year_part inacc_part
| year_part
| day_part tdf_part inacc_part
| day_part tdf_part
| day_part inacc_part
| day_part
| year_part Z
| year_part Z inacc_part
| year_part day_part Z inacc_part
| day_part Z inacc_part
| day_part Z

year_part : number - number - number -
