Hi Sald,
U can see the below code.
REPORT ztest_time_conv.
DATA: hour(2) TYPE n,
min(2) TYPE n,
sec(2) TYPE n,
tim TYPE i.
DATA: time TYPE p DECIMALS 2.
DATA: timeformat TYPE sy-uzeit.
time = '1.38'.
tim = time * 3600.
hour = tim DIV 3600.
tim = tim MOD 3600.
min = tim DIV 60.
sec = tim MOD 60.
CONCATENATE hour min sec INTO timeformat.
WRITE timeformat.
BREAK-POINT.
