Hello everyone  
I am translating an R program into Julia.  
I have a problem because I assign the type POSIXct (POSIXct class stores date/time values as the number of seconds since January 1, 1970) to one of the columns of my dataframe in R :

```julia
class(data$MaterialExpectedDate) <- "POSIXct" 

```

I can’t find the equivalent of this format in Julia. Do you know a way to get this format ?

Thank you,

---

```julia
julia> using Dates

julia> datetime2unix(DateTime(1970, 1, 1))
0.0

julia> datetime2unix(DateTime(1970, 1, 2))
86400.0

```
