Formula for practitioners

$^{\mathit{max}}_{c \in g} \mathit{endt}(c) - ^{\mathit{min}}_{c \in g} \mathit{startt}(c)$

$\mathit{endt}(c)$ returns the end timestamp of case $c$.
$\mathit{startt}(c)$ returns the start timestamp of case $c$.
$^{\mathit{max}}_{c \in g}$ and $^{\mathit{min}}_{c \in g}$ indicate that the maximum end time and minimum start time are taken across all cases in the group $g$.
