time_add_day

Adds a day onto the time, using local time.

Note that if clocks go forward due to daylight savings time, there are some non-existent local times, so the hour may be changed to make it a valid time. This also means that it may not be wise to keep calling time_add_day to step through a certain period - if the hour gets changed to make it valid time, any further calls to time_add_day will also return this hour, which may not be what you want.

Parameters:

time	A time_t value.
days	Number of days to add.

Returns:

a time_t value containing time plus the days added.
