QTime

QTime is a class in the Qt framework that represents a time of day without an associated date. It stores the hour, minute, second and millisecond components, typically in the range from 00:00:00.000 to 23:59:59.999. A QTime object can be null to represent an uninitialized or invalid time.

Constructors include a default null constructor QTime(), and a value-based constructor QTime(int h, int m, int s, int ms = 0). The class provides static helpers such as QTime::currentTime() to obtain the current system time, QTime::fromString(const QString &string, const QString &format) to parse a time string according to a format, and QTime::fromMSecsSinceStartOfDay(int) for millisecond-based creation.

QTime exposes accessors hour(), minute(), second(), and msec() for retrieving components. It also supports mutating via setHMS(int h, int m, int s, int ms = 0). Formatting is performed with toString(const QString &format). For arithmetic, there are methods to add or subtract time in seconds or milliseconds, and to compute differences with msecsTo(const QTime &) or secsTo(const QTime &). The comparison operators enable ordering and equality checks.

QTime is often used for time-of-day calculations, scheduling, or as part of a QDateTime pair. It does not store a date or time zone; for full date-time representations, QDateTime or QTimeZone should be used.
