datetime start derivations
- datetime start from datetime and stop - symbol - description - unit - variable name - \(t\) - datetime (mid point) - \(s\) since 2000-01-01 - datetime {:} - \(t_{s}\) - datetime start - \(s\) since 2000-01-01 - datetime_start {:} - \(\Delta t\) - time duration - \(s\) - datetime_length {:} - The pattern : for the dimensions can represent {time}, or no dimension at all. \[t_{s} = t - \frac{\Delta t}{2}\]
- datetime start from range - symbol - description - unit - variable name - \(t^{B}(l)\) - datetime boundaries (\(l \in \{1,2\}\)) - \(s\) since 2000-01-01 - datetime_bounds {:,2} - \(t_{s}\) - datetime start - \(s\) since 2000-01-01 - datetime_start {:} - The pattern : for the dimensions can represent {time}, or no dimension at all. \[t_{s} = t^{B}(1)\]
