Who set the time in eighteenth-century Istanbul and how? When did government officials arrive at their offices? How did new technologies like the train and the steamer affect conventions of punctuality and lateness and what were the social and political implications of waiting? This book analyzes the "temporal culture" of the late Ottoman Empire and follows its transformation from the late eighteenth century to the establishment of the Turkish Republic. In an attempt to cope with the rapid changes that swept the region during that period, various bodies of the Ottoman state began to subject work routines to mechanical clocks and schedules in order to achieve higher levels of regularity, punctuality and efficiency. A new time web gradually spread from governmental facilities such as military bases, bureaus and schools to traffic arteries and city centers, subjecting more and more people to clock time and the new conventions linked to it. These changes, in turn, raised difficulties, tensions and even resistance, which were related not only to practical problems of coordination, but also to questions of identity, ideology and cultural orientation. The clocks of the early twentieth century thus showed Ottoman time with all its complexity.
