DiscretelyTimeVaryingTraits

Trait	Type	Default	Description
`fromContinuous`	`string`	`nearest`	Specifies how a continuous time (e.g. the timeline control) is mapped to a discrete time for this dataset. Valid values are: * `nearest` - the nearest available discrete time to the current continuous time is used. * `next` - the discrete time equal to or after the current continuous time is used. * `previous` - the discrete time equal to or before the current continuous time is used.
`showInChartPanel`	`boolean`		Whether to plot data availability on a chart.
`disableDateTimeSelector`	`boolean`		When true, disables the date time selector in the workbench
`multiplierDefaultDeltaStep`	`number`	`2`	The multiplierDefaultDeltaStep is used to set the default multiplier (see `TimeVaryingTraits.multiplier` trait) - it represents the average number of (real-time) seconds between (dataset) time steps. For example, a value of five would set the `multiplier` so that a new time step (of this dataset) would appear every five seconds (on average) if the timeline is playing. This trait will only take effect if `multiplier` is not explicitly set.

If the system time is before `Start Time`, `Start Time` is used. * `none` - do not automatically set an initial time This value is ignored if `Current Time` is specified.
`startTime`	`string`	`2026-02-11T16:16:19.747000000Z`	The earliest time for which this dataset is available. This will be the start of the range shown on the timeline control.
