UTO CosTime::UTO::absolute_time

(

)

This operation calculates an absolute time taking the current UTO contents as a time relative to the current system time.

Returns:

time in object + system time.

TimeComparison CosTime::UTO::compare_time	(	in ComparisonType	comparison_type,
		in UTO	ut
	)

Compares this UTO to another.

comparison_type - Either IntervalC, in which case the comparison will take into account the error envelope, or MidC, in which case it will not. uto - The object being compared to this one.

Returns:

TCLessThan if the time in this object is earlier than that in uto, TCGreaterThan if it is later, TCEqualTo if they are the same and TCIndeterminate if the error envelopes overlap and the comparison_type is IntervalC.

TIO CosTime::UTO::interval

(

)

Generates an interval based on this UTO.

Returns:

A TIO with bounds set to the possible values of this UTO when the error is taken into account.

TIO CosTime::UTO::time_to_interval

(

in UTO

ut

)

Generates the interval between this UTO and another.

uto - specifies one bound of the interval. This object is the other.

Returns:

A TIO with bounds set to the midpoints of the two UTOs.

Member Data Documentation

readonly attribute TimeBase::InaccuracyT CosTime::UTO::inaccuracy

Specifies the uncertainty associated with the time in the UTO, in 10E-7 seconds.

readonly attribute TimeBase::TdfT CosTime::UTO::tdf

Specifies the time zone in which the UTO was created, expressed in minutes from Greenwich.

Positive values represent zones East of the meridian.

readonly attribute TimeBase::TimeT CosTime::UTO::time

Specifies the time represented by the UTO.

It is expressed as a number of 10E-7 seconds since a defined point. For absolute time this is 15th October 1582 00:00:00 GMT.

readonly attribute TimeBase::UtcT CosTime::UTO::utc_time

Specifies the time, error and zone represented by this UTO in a single structure.
