QDateTime QDateTime::fromTime_t(uint seconds)Returns a datetime whose date and time are the number of seconds that have passed since 1970-01-01T00:00:00, Coordinated Universal Time (Qt::UTC) and converted to Qt::LocalTime. On systems that do not support time zones, the time will be set as if local time were Qt::UTC.
Note: This function is deprecated. Please use fromSecsSinceEpoch() in new code.
This function was introduced in Qt 4.2.
See also toTime_t() and setTime_t().

QDateTime QDateTime::fromTime_t(uint seconds, Qt::TimeSpec spec, int offsetSeconds = 0)Returns a datetime whose date and time are the number of seconds that have passed since 1970-01-01T00:00:00, Coordinated Universal Time (Qt::UTC) and converted to the given spec.
If the spec is not Qt::OffsetFromUTC then the offsetSeconds will be ignored. If the spec is Qt::OffsetFromUTC and the offsetSeconds is 0 then the spec will be set to Qt::UTC, i.e. an offset of 0 seconds.
Note: This function is deprecated. Please use fromSecsSinceEpoch() in new code.
This function was introduced in Qt 5.2.

QDateTime QDateTime::fromTime_t(uint seconds, const QTimeZone &timeZone)Returns a datetime whose date and time are the number of seconds that have passed since 1970-01-01T00:00:00, Coordinated Universal Time (Qt::UTC) and with the given timeZone.
Note: This function is deprecated. Please use fromSecsSinceEpoch() in new code.
This function was introduced in Qt 5.2.
See also toTime_t() and setTime_t().
Sets the date and time given the number of seconds that have passed since 1970-01-01T00:00:00, Coordinated Universal Time (Qt::UTC). On systems that do not support time zones this function will behave as if local time were Qt::UTC.
Note: This function is deprecated. For new code, use setSecsSinceEpoch().
See also toTime_t().
Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, Coordinated Universal Time (Qt::UTC).
On systems that do not support time zones, this function will behave as if local time were Qt::UTC.
Note: This function returns a 32-bit unsigned integer and is deprecated.
If the date is outside the range 1970-01-01T00:00:00 to 2106-02-07T06:28:14, this function returns -1 cast to an unsigned integer (i.e., 0xFFFFFFFF).
To get an extended range, use toMSecsSinceEpoch() or toSecsSinceEpoch().
See also toSecsSinceEpoch(), toMSecsSinceEpoch(), and setTime_t().
