julia> convert(DateTime, events[1,2])

julia> convert(DateTime, events[:,2])
ERROR: MethodError: Cannot convert an object of type Array{Int64,1} to an object of type DateTime
This may have arisen from a call to the constructor DateTime(…),
since type constructors fall back to convert methods.

julia> convert.(DateTime, events[:,2])
ERROR: MethodError: no method matching size(::Type{DateTime})
Closest candidates are:
size{N}(::Any, ::Integer, ::Integer, ::Integer…) at abstractarray.jl:48
size(::BitArray{1}) at bitarray.jl:39
size(::BitArray{1}, ::Any) at bitarray.jl:43

I think convert. should work in Julia 0.6 but if you want something that’ll work in Julia 0.5 then this will work:

map((x) -> convert(DateTime,x),events[:,2])
