# frame_exact¶

## Description¶

Specify the exact relative time frame for a window context. This is the exact version of frame(), where the window frame start and end times are exactly “Valid From” minus “back” and “Valid To” plus “ahead”. Evaluation of exact window frames can be slow when the data volume is large.
