.. _auto_curves_get_sync_offset:

* COMPUTE THE SYNC TIME*
========================

Computes the time-axis synchronisation offset between two curves by finding the optimal shift that aligns Curve 2 to Curve 1. Use this worker when two time-history signals need to be temporally aligned before comparison or further processing.

     - Target curve (time-history vector) whose time offset relative to Curve 1 is to be determined; typically the test or comparison signal.
