15-Sep-2019 11:00:00

15-Sep-2019 11:30:00

15-Sep-2019 12:00:00

15-Sep-2019 12:30:00

15-Sep-2019 13:00:00

15-Sep-2019 13:30:00

15-Sep-2019 13:31:00

T = datetime(Time, 'InputFormat','dd-mm-yyyy HH:mm:ss', 'TimeZone','Asia/Kolkata')
T.TimeZone = 'Asia/Kolkata'

You should be assigning UTC to T.TimeZone

s_ist = '15-Sep-2019 13:31:00';                     % datetime string for ist
d_ist = datetime(s_ist, 'TimeZone', '+05:30');      % datetime for ist
d_utc = datetime(d_ist, 'TimeZone', '+00:00')       % datetime for utc

d_utc = datetime
