כל ההבדל בין האשכנזים לספרדים הוא, שאנחנו מחשבים את היום מעמוד השחר עד 20 דקות אחרי השקיעה, ואילו האשכנזים מחשבים את היום בחשבון אחר, ולדעת הגאון מוילנא היום מתחיל מהנץ החמה ועד השקיעה, ולפי"ז יוצא זמן ארבע שעות זמניות בחשבון אחר.
All the difference between Ashkenaz and Sefarad is, we[Sefarad] calculate the day from Dawn until 20 minutes after sunset, while Ashkenaz use a different clculation, according to the Vilna Ga'on the day starts at sunrise, hence different times for 4 Sha'ot Zemaniot.
