datetime bounds derivations

  1. 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}
