[SCCC] N1MM+ question

N1MM+= Question

When the "Show Bearing Information" is checked to show, in the Entry Window
of N1MM+, I see the following for PY5AMF:
.
Regional Hdg 113 (deg) LP 293 (deg) 5228mi 8414km SR 09:00Z
.
I can see the Heading and Long Path heading
as well as the distance in mi and km.
But what is the **SR 09:00Z**  ?
Can't find it in the manual or help search.
.
Thanks.
