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.

Public predicates

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

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

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
