ccsds_cds(DaySegmentOctets,SubmillisecondOctets,Epoch)

• DaySegmentOctets - Number of day segment octets. Supported values are 2 and 3.
• SubmillisecondOctets - Number of submillisecond octets. Supported values are 0, 2, and 4.
• Epoch - Epoch used when converting to and from Unix seconds. Supported values are ccsds_epoch and unix_epoch. CCSDS day segmented time code parser and generator.

Public predicates

.. index:: days/2 .. _ccsds_cds/3::days/2:

days/2 ^^^^^^^^^^

Extracts the day segment value from a CDS time term.

| Compilation flags: | static

| Template: | days(TimeCode,Days) | Mode and number of proofs: | days(+compound,-integer) - one

---

.. index:: milliseconds/2 .. _ccsds_cds/3::milliseconds/2:

milliseconds/2 ^^^^^^^^^^^^^^^^^^

Extracts the millisecond-of-day value from a CDS time term.

| Compilation flags: | static

| Template: | milliseconds(TimeCode,Milliseconds) | Mode and number of proofs: | milliseconds(+compound,-integer) - one

---

.. index:: submilliseconds/2 .. _ccsds_cds/3::submilliseconds/2:

submilliseconds/2 ^^^^^^^^^^^^^^^^^^^^^

Extracts the optional submillisecond value from a CDS time term. Two-octet objects use microseconds; four-octet objects use picoseconds within the millisecond.

| Compilation flags: | static

| Template: | submilliseconds(TimeCode,Submilliseconds) | Mode and number of proofs: | submilliseconds(+compound,-integer) - zero_or_one
