Detailed Description

encoding rules. The application representation of the TIME value is simply a String, whose content shall be a TimeValue, as defined in X.680. Some notes on formatting:

A year/century should have a leading plus sign if and only if the year/century > 9999/99.
A year/century having 5/3 or more digits should never include leading zeros. A value with a year of 1985 has the property Year="Basic" and is formatted with only 4 digits, never more.
A year/century should never have fewer than four/two digits. This is the only case where leading zeros may be used. + When FRACTION is used to specify a number of fraction digits, the string representation must have precisely that many digits for the fraction. Note that FRACTION is not to be used with DURATION.

Member Function Documentation

◆ ConvertToDER()

static String ConvertToDER ( String timeValue )

static

Return the DER representation of a TimeValue. Given some TimeValue, this function returns a string representing the characters that should be encoded for that TimeValue when using DER.

This can be invoked for values of type TIME. Its result is not correct for values of type DATE, TIME-OF-DAY, DATE-TIME, or DURATION, all of which require removing certain characters that are not removed for values of type TIME. However, for DURATION, this function can first be used and then the leading P removed.

◆ DecodeDate()

static System.String DecodeDate	(	Asn1PerDecodeBuffer	source,
		int	flags
	)

static

Decode a date value from the given source.

This should be used for types having Basic="Date".

Parameters

source
flags

Returns: ASN.1 TimeValue representation of decoded value

Referenced by Asn1Date.Encode().

◆ DecodeDateTime()

static System.String DecodeDateTime	(	Asn1PerDecodeBuffer	source,
		int	flags
	)

static

Decode a date-time value from the given source.

This should be used for types having Basic="Date-Time".

Parameters

source
flags	Indicates what fields are expected. The flags should indicate a complete date (YMD, YWD, or YD) and at least an hour component.

Returns: The value represented as an ASN.1 TimeValue

◆ DecodeDuration()

static System.String DecodeDuration	(	Asn1PerDecodeBuffer	source,
		bool	recurring
	)

static

Decode a (possibly recurring) duration from the given source.

This should be used for types having Basic="Interval" or "Rec-Interval" and Interval-type="D"

Parameters

source
recurring	true if the duration is a recurring duration

Returns

◆ DecodeTime()

static System.String DecodeTime	(	Asn1PerDecodeBuffer	source,
		int	flags
	)

static

Decode a time value from the given source.

This should be used for types having Basic="Time".

Parameters

source
flags	Indicates the expected fields.

Returns

◆ EncodeDate()

static void EncodeDate	(	Asn1PerEncoder	encoder,
		System.String	val,

encoder. This should be used for types having Basic="Date".

Parameters

static

Encode a datetime value.

This should be used for types having Basic="Date-Time".

Parameters

◆ EncodeDuration()

static void EncodeDuration	(	Asn1PerEncoder	encoder,
		System.String	val,
		bool	recurring
	)

static

Encode a duration according to PER.

This should be used for types having Basic="Interval" or "Rec-Interval", and Interval-type="D".

Parameters

encoder
val	The duration
recurring	true if value represents a recurring duration.

◆ EncodeTime()

static void EncodeTime	(	Asn1PerEncoder	encoder,

	)

static

Encode a time value.

This should be used for types having Basic="Time".

Parameters

encoder
val
flags

Member Data Documentation

◆ ANY

const int ANY = 0x8000

For PER, when ANY is combined with CENTURY/YEAR, it indicates that the type is constrained to values with Year=Ln or NEGATIVE (as for the defined types named ANY-*), while absence of ANY indicates the type is constrained to values with Year=Basic or Proleptic. There is a little inconsistency here, however. At present, code generation will use the DT_ANY* constants for a type that has Year=Negative, or that has Year=Ln for some n. By contrast, the defined types named ANY-* include values that have either Year=Negative or Year=L5. I think this discrepancy doesn't matter though, because PER uses the same encodings whether type includes:

only values with Year=Ln
only values with Year=L5
only values with Year=Negative
only values with Year=Negative or Year=L5

The ANY flag's presence/absence is irrelevant to OER, as OER's optimized encodings do not depend on the Year property.

◆ CENTURY

const int CENTURY = 0x4000

Flags for Date properties. Each flag indicates a particular component that is required for dates.

◆ DIFF

const int DIFF = 0x0020

Indicates a time includes a timezone difference from UTC.

DIFF and UTC should never appear together.

◆ DURATION

const int DURATION = 0x0010

Indicates a duration.

No other flags should be used with DURATION.

◆ FRACTION

const int FRACTION = 0x000F

This is a mask that is used to mark off the bits used for

the number of decimal places for a fraction.

value & FRACTION = # of decimal places

◆ UTC

const int UTC = 0x0040

Indicates a time is UTC. Its string format includes the 'Z' timezone designator.

◆ WEEK

const int WEEK = 0x0800

Week is present.

When used for a duration (with DURATION), the following are excluded: CENTURY, YEAR, MONTH, DAY, HOURS, MINUTES, SECONDS

When used for a date/datetime (without DURATION), MONTH is excluded.
