Do you need the result to be in a time type? If it’s of some numeric type but represents milliseconds then just do the conversion. `seconds = delta/1000`

If you really need it in a time type then you can extend your [other question](https://discourse.julialang.org/t/how-to-convert-to-datetime-all-column-or-array/2421/2).

```julia
julia> t1 = map((x) -> convert(DateTime,x),events[:,1])
julia> t2 = map((x) -> convert(DateTime,x),events[:,2])
julia> delta = t2 - t1
10-element Array{Base.Dates.Millisecond,1}:
 75631000 milliseconds 
 6031000 milliseconds  
 13531000 milliseconds 
 12685000 milliseconds 
 632000 milliseconds   
 21631000 milliseconds 
 212430000 milliseconds
 30000 milliseconds    
 30000 milliseconds    
 30000 milliseconds 

```

or

```julia
julia> time = map((x) -> convert(DateTime,x),events)
10×2 Array{DateTime,2}:
