Yes, you are right. The term stuck in my head from an astronomy course
I took in the distant past. About the only point in my life where I
studied all of the major time systems and how they inter-related...
Apparently without any great retention... sigh!
Local Solar Time is the LST I was thinking of... only, I guess 00:00:00
is high noon in LST.... Maybe Local Sundial Time?
