Hi, I'm working with two time series with the time specified in Julian time. I need to work out the difference between the start time in each data set. Anyone know how?? Thanks D

Please post the format of your inputs and the wanted output. Are you talking of a DOUBLE vector or a cell string?

>> d1 = juliandate(datetime('today'))
d1 =
2458017.5
>> d2 = d1 + 1234
d2 =
2459251.5
>> between(datetime(d1,'ConvertFrom','juliandate'), datetime(d2,'ConvertFrom','juliandate'))
ans =
calendarDuration
3y 4mo 16d
>> between(datetime(d1,'ConvertFrom','juliandate'), datetime(d2,'ConvertFrom','juliandate'),'days')
ans =
calendarDuration
1234d
