Hi all,

I was wondering if there's a function to sanitize a date vector (or add a time in seconds to a date vector). For example, if I want to find the date and time 1 millions seconds in the future:

present = datevec(now);
look_ahead = 1e6;  % fast forward 1 million seconds
% the date vector for the future
future = present; 
future(end) = future(end) + look_ahead;
% print the date one million seconds in the future
future_str = datestr(future)  % not what's intended
% Work around it by converting look_ahead to a time stamp.
% This work around is "clunky", loses precision, and is not guaranteed to be correct
look_ahead_stamp = look_ahead / (24*60*60); % if only all days had the same number of seconds
future_str = datestr(datenum(present) + look_ahead_stamp)
% Ideal Solution:
future = SantizeDateVec(future);  % does this function exist?
datestr(future)
