![]() There must be at least one section after the "T". The first occurrence, if any, of an hour, minute or second section.Īt least one of the four sections must be present, and if "T" is present The sections have suffixes in ASCII of "D", "H", "M" and "S" forĭays, hours, minutes and seconds, accepted in upper or lower case. There are then four sections, each consisting of a number and a suffix. The ASCII letter "P" is next in upper or lower case. If negative, the whole period is negated. The string starts with an optional sign, denoted by the ASCII negative On the ISO-8601 duration format PnDTnHnMn.nS with days This will parse a textual representation of a duration, including the Obtains a Duration from a text string such as PnDTnHnMn.nS. Implementation Requirements: This class is immutable and thread-safe. The equals method should be used for comparisons. ( =), identity hash code, or synchronization) on instances ofĭuration may have unpredictable results and should be avoided. See Instant for a discussion as to the meaning of the second and time-scales.Ĭlass use of identity-sensitive operations (including reference equality This difference only impacts durations measured near a leap-second and should not affect The scientific "SI second" definition based on atomic clocks. The duration is measured in "seconds", but these are not necessarily identical to The model is of a directed duration, meaning that the duration may be negative. Representing nanosecond-of-second, which will always be between 0 and 999,999,999. ![]() To achieve this, the class stores a long representing seconds and an int The range of a duration requires the storage of a number larger than a long. This is greater than the current estimated age of the universe. The duration uses nanosecond resolution with a maximum value of the seconds that canīe held in a long. See Period for the date-based equivalent to this class.Ī physical duration could be of infinite length.įor practicality, the duration is stored with constraints similar to Instant. In addition, the DAYS unit can be used and is treated asĮxactly equal to 24 hours, thus ignoring daylight savings effects. It can be accessed using other duration-based units, such as minutes and hours. This class models a quantity or amount of time in terms of seconds and nanoseconds. You can use a formula field to re-process your duration into a plain number, then use that formula field as your y-axis.A time-based amount of time, such as '34.5 seconds'. While Duration fields are numeric fields, they are not valid options for the y-axis of a Chart extension. Why is my duration field not showing as a valid option for the y-axis of my chart? You'll need to account for this in your formula by dividing by 60 if you want to calculate in minutes, 3600 (60 * 60) for hours, etc. FAQs Why does my duration field's value increase when I use it in a formula?ĭuration fields store values in seconds, regardless of the formatting option you choose to display visually. Note that when using DATEADD()you should make sure the timezone formatting is consistent between the date field you are using and the formula field returning it (e.g. You can use a formula like, '**seconds**'). You can use simple math operators (like + for addition, - for subtraction, and so on) with durations. Once you do that, you can choose the specific Duration Format, e.g. To format as a duration in a computed field, go to the field customization menu, click the Formatting tab, and select Duration from the Format dropdown. You can also format numeric formulas, lookups, or rollup fields as a duration-for example, multiplying a duration by a number, or rolling up the sum of a duration field from linked records. ![]() For example, if you select h:mm formatting, but then input 0.50, the value duration outputted would round up to 0:01 since 0.50 represents a half of a second. When formatting the output of the duration field any fractional values will round up to the next closest value.
