Format the current time in Python Once we have a time.struct_time object, we can format it into a string so that it can be further processed by another program. We can do so by calling time.strftime(format[, t]) with the current time object as the argument t The QTime class provides clock time functions. A QTime object contains a clock time, i.e. the number of hours, minutes, seconds, and milliseconds since midnight. It can read the current time from the system clock and measure a span of elapsed time Get current time Get the current calendar time as a value of type time_t . The function returns this value, and if the argument is not a null pointer , it also sets this value to the object pointed by timer
#热议# 翻译软件越来越强大,大学生还有必要学外语吗 It is a combination of the QDate and QTime classes. It can read the current datetime from the system clock. It provides functions for comparing datetimes and for manipulating a datetime by adding a number of seconds, days, months or years Returns the current calendar time encoded as a std::time_t object, and also stores it in the object pointed to by arg, unless arg is a null pointer
