Hi, I attached 'Time' variable from 1995-01-01~2021-12-15 and it is monthly data.
It's units = 'days since 1950-01-01 00:00:00
I want to convert it yyyy-mm .
This is what i tried
  1. TT=datetime(1995,1,1)+hours(time); -> It starts 1996-11~
  2. TT=years(time) ->Absolutely wrong
  3. TT=datetime(time,'ConvertFrom','epochtime','Epoch','1950-01-01');->It's unit is seconds. Wrong
Please help me. Thanks.

Ran in:
load Time.mat
%time
dt = datetime("1950-01-01 00:00:00") + days(time)
dt = 324×1 datetime array
