Here is how I would do it. I put your example data into a file I named
"time_test.txt".

;*********************************************************** ******
filename = 'time_test.txt'

; Read the data in the file into strings.
rows = File_Lines(filename)
data = StrArr(rows)
OpenR, lun, filename, /Get_Lun
ReadF, lun, data
Free_Lun, lun

; Set up output data arrays.
bx_array = FltArr(rows)
by_array = FltArr(rows)
bz_array = FltArr(rows)
hour = IntArr(rows)
minute = IntArr(rows)

; Parse each row and print it out in the correct format.
FOR j=0,rows-1 DO BEGIN
date = StrMid(data[j], 0, 9)
time = StrMid(data[j], 11, 23)
subString = StrMid(data[j], 24)
ReadS, subString, bx, by, bz
parts = StrSplit(time,':', /Extract)
hour[j] = Fix(parts[0])
minute[j] = Fix(parts[1])
bx_array[j] = bx
by_array[j] = by
bz_array[j] = bz
Print, String(hour[j],Format='(I2.2)') + '.' + $
String(minute[j],Format='(I2.2)'), $
bx_array[j], by_array[j], bz_array[j], $
FORMAT='(A5, 2x, 3(F0.5, 2x))'
ENDFOR

END
;*********************************************************** ******

Cheers,

David
