TimeSeriesQ
TimeSeriesQ [expr]
gives True if expr is a valid TimeSeries object, and False otherwise.
Details
- TimeSeriesQ tests whether an input is a valid TimeSeries object.
- A valid time series has head TimeSeries and stores same-length lists of times and values.

Test whether an object is a valid time series:
TimeSeries[{70.2, 78.5, 75.1}, {Today}]TimeSeriesQ[%]Test whether FromTabular returned a valid time series:
FromTabular[Tabular[Association["RawSchema" -> Association["ColumnProperties" ->
Association["Time" -> Association["ElementType" -> "Integer64"],
"Value" -> Association["ElementType" -> "Integer64"]], "KeyColumns" -> None,
"Backend" -> "WolframKernel"], "Options" -> {},
