I think Pavels solution will always be true as Lasttime is now defined
identical to this time (ie mstime)
try these changes (marked by ;**)#
cheers
Martin

;** add
Lasttime = -1 ; dummy value which should always be different from mstime
;**
while not EOF(lun) do begin
readf, lun, line
line=strjoin(strsplit(line,'"',/extract),/single)
;** delete Lastline here
values=strsplit(line,',',/extract)
msdate=double(values(0))
mstime=double(values(1))
;** modify below so that you dont detect the first loop as changed
if (Lasttime ne -1) and (Lasttime ne mstime) then begin
;**
print,'', Lasttime, mstime, ' Zeiten sind ungleich!'
Zeitpunkt=mstime2sqlts(msdate,mstime)
insertstr='INSERT INTO ' + table + ' VALUES ("'
+sqlts2datetimestr(Zeitpunkt) + '"'
for i=2,(n_elements(fields)-1) do insertstr=insertstr + ', ' + values(i)
insertstr=insertstr+ ' ) ;'
;;;XX
;dbobj->ExecuteSQL,insertstr
endif else begin
print,'', Lasttime, mstime, ' Zeiten sind gleich!'
endelse
;**
Lasttime = mstime ; now set to mstime ready for next loop
;**
endwhile
