datetime bounds derivations
- datetime ranges from start and stop - symbol - description - unit - variable name - \(t^{B}(l)\) - datetime boundaries (\(l \in \{1,2\}\)) - \(s\) since 2000-01-01 - datetime_bounds {:,2} - \(t_{e}\) - datetime stop - \(s\) since 2000-01-01 - datetime_stop {:} - \(t_{s}\) - datetime start - \(s\) since 2000-01-01 - datetime_start {:} - The pattern : for the dimensions can represent {time}, or no dimension at all. \begin{eqnarray} \phi^{B}(1) & = & t_{s} \\ \phi^{B}(2) & = & t_{e} \end{eqnarray}
