 | **Ending Depth**	| Depth where current segment ends; a different depth from the previous segment creates a transition segment for ascent or descent, keeping the same depth creates a segment at the given depth. By default the planner uses the measurement for length set in the preferences (meters for most users) - this can be overridden by explicitly specifying 'm' or 'ft'.
-| **Segment Time**	| Enter time in minutes; segment duration / relative time is indicated by a '+':  '+3' or '+3:00' creates a segment that lasts 3 minutes, a bare number like '7' is used for a segment that ends 7 minutes after the start of the dive.
+| **Segment Time**	| Enter time in minutes; segment duration / relative time is indicated by a '+':  '+3' or '+3:00' creates a segment that lasts 3 minutes, an absolute time is indicated by @ character. Time '@7:30' means that the segment ends 7 minutes and 30 seconds after the start of a dive.
 | **Gas Used**		| Breathing gas mix used; the parser is reasonably flexible and understands terms like AIR, EAN32, 36% or 15/50 (compressed air, 32% nitrox, 36% nitrox or 15% O₂ / 50% He trimix, respectively); leaving this field empty indicates continued use of the previous gas, air by default
