+    Napišite razred Time, ki naj ima:
+        privatne instančne spremenljivke:
+            hour,
+            minute in
+            second.
+        razredne spremenljivke:
+            maxHour, ki je konstanta in predstavlja maksimalno vrednost, in sicer 24
+            noonHour, ki je konstanta in predstvalja opoldne, in sicer ima vrednost 12
+        javni konstruktor s 3 parametri (pri tem pazite, da nastavite vrednosti le, če je čas veljaven, sicer nastavite vse vrednosti na 0),
+        javno metodo toString, ki vrne čas kot string, in sicer v formatu hh:mm:ss (npr. 14:05:30),
+        javno metodo toString12HourFormat, ki vrne čas kot string, vendar je čas prilagojen za 12-urni časovni sistem. Torej je potrebno ustrezno spremeniti čas in na koncu dodati še "AM"/"PM". Format pri tem zapisu je hh:mm:ss XM (npr. 18:03:01 --> 06:03:01 PM),
+        javno razredno metodo isTimeValid(unsigned int hour, unsigned int minute, unsigned int second), ki preveri, ali je možen čas glede na podane podatke. Potrebno je upoštevati maksimalne vrednosti, in sicer 23:59:59. Primer: isTimeValid(14, 3, 43) vrne true, isTimeValid(16, 67, 91) vrne false.
+        javno razredno metodo parse(std::string time), ki prejme čas v obiki niza (v formatu hh:mm:ss), razbere posamezne vrednosti in vrne čas tipa Time.
+
+V glavnem programu prikažite delovanje vseh metod. Ustvarite vsaj 5 različnih objektov razreda Time in na ta način preverite, ali metode pokrivajo vse možne scenarije.
+
+    Ostali napotki pri reševanju naloge:
+        Če potrebujete kako metodo get ali set (za posamezno instančno spremenljivko), si jo zapišite.
+        V nalogi uporabite kazalec this na vseh mestih, kjer je smiselno.
+        V nalogi uporabite določilo const pri vseh metodah, kjer je smiselno.
