JulianDate Methods |
The JulianDate type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | Add |
Adds a Duration to this Julian date, producing a new Julian date.
|
| AddClamped |
Adds a Duration to this Julian date, producing a new Julian date.
Unlike Add(Duration), this method will clamp the result to the valid range
of values for JulianDate rather than throwing an exception.
In most cases, Add(Duration) should be used instead.
|
| AddDays |
Adds the specified number of days to this date and returns the new date.
|
| AddHours |
Adds the specified number of hours to this date and returns the new date.
|
| AddMinutes |
Adds the specified number of minutes to this date and returns the new date.
|
| AddSeconds |
Adds the specified number of seconds to this date and returns the new date.
|
| CompareTo(JulianDate) |
Compares this instance with another instance of the same type.
|
| CompareTo(Object) |
Compares this instance with another instance of the same type.
|
| DaysDifference |
Computes the number of days that have elapsed from this Julian date to the
other Julian date.
|
| Equals(JulianDate) |
Returns true if this date exactly equals another date. To be considered equal, the Day
and SecondsOfDay properties must be identical when converted to a common time standard.
It is highly recommended that you use EqualsEpsilon(JulianDate, Double) or IsIdentical(JulianDate)
instead of this method.
|
| Equals(Object) |
Returns true if this date exactly equals another date. To be considered equal, the Day
and SecondsOfDay properties must be identical when converted to a common time standard.
It is highly recommended that you use EqualsEpsilon(JulianDate, Double) or IsIdentical(JulianDate)
instead of this method.
(Overrides ValueTypeEquals(Object).) |
| EqualsEpsilon |
Returns true if this date is within epsilon seconds of the
specified date. That is, in order for the dates to be considered equal (and for
this function to return true), the absolute value of the difference between them, in
seconds, must be less than or equal to epsilon.
|
 | GetCenterOfWindow |
Divides time into windows, each of length windowLength seconds, with the first
window centered on referenceEpoch. Then, identifies which window contains
date and returns the date that is at the center of that window. This is helpful
for computing a discrete value for a range of Julian dates.
|
| GetHashCode |
Returns a hash code for this instance, which is suitable for use in hashing algorithms and data structures like a hash table.
(Overrides ValueTypeGetHashCode.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsIdentical |
Returns true if this date is identical to another date. Unlike Equals(JulianDate), this method will
consider two dates with different time standards to be different even if the dates represent the same
moment when expressed in the same time standard.
|
| JulianDateToYearFraction |
Computes the fraction of the year corresponding to the given Julian date.
|
| MinutesDifference |
Computes the number of minutes that have elapsed from this Julian date to the
other Julian date.
|
| SecondsDifference |
Computes the number of seconds that have elapsed from this Julian date to the
other Julian date.
|
| Subtract(Duration) |
Subtracts a Duration from this Julian date, producing a new
Julian date.
|
| Subtract(JulianDate) |
Subtracts another Julian date from this Julian date.
|
| SubtractDays |
Subtracts the specified number of days from this date and returns the new date.
|
| SubtractHours |
Subtracts the specified number of hours from this date and returns the new date.
|
| SubtractMinutes |
Subtracts the specified number of minutes from this date and returns the new date.
|
| SubtractSeconds |
Subtracts the specified number of seconds to this date and returns the new
date.
|
| ToDateTime |
Converts this JulianDate to a .NET standard
DateTime with a default time standard of Coordinated Universal
Time.
|
| ToDateTime(TimeStandard) |
Converts this JulianDate to a .NET standard
DateTime expressed in the specified time standard.
|
| ToGregorianDate |
Converts this JulianDate to a GregorianDate with a
default time standard of Coordinated Universal Time.
|
| ToGregorianDate(TimeStandard) |
Converts this JulianDate to a GregorianDate
expressed in the specified time standard.
|
| ToString |
Returns the value of this JulianDate in the standard format.
(Overrides ValueTypeToString.) |
| ToTimeStandard |
Converts this JulianDate to the specified time standard.
|
| TryConvertTimeStandard |
Try to convert this JulianDate to the specified
TimeStandard, if the specified TimeStandard is
capable of representing this time.
