Indeed, you may call things 'energy' in any way you want.
But back to basics: something that you call 'energy'
isn't really an energy in a physical sense
unless you can show how it can be converted
(partly, and at least in principle) to 1/2 mv^2.

With conservation of energy of course,

 And, similiarly (sic), somethinf (sic) [SR]
is calling "time" - is not a time in the real sense
ubless (sic) it's  absolute/obswever (sic) independent.

"similiarly", "somethinf", "ubless", "obswever". High on drugs today?
Anyway, you're right in the sense that coordinate time in SR
is partly conventional (i.e. depends on clocks synchronization)
and is, at the end of day when one performs real experiments,
only an intermediate value used in calculation.
Only colocated measurements can be done.
Maybe you will, one day, understand what SR is after all Wozniak.
