I know that for calculations, the difference between two datetimes is useful, when in form of seconds (or another unit). My question is: to get this difference in form of days H:M:S, do I need to write a function or is there some easy trick?
julia> using Dates
julia> ts1 = DateTime("2019-10-01T12:00:00.00")
julia> ts2 = DateTime("2019-10-02T03:23:40.00")
15 hours, 23 minutes, 40 seconds
Some more manipulation:
julia> using Unitful
julia> using Pipe
julia> @pipe ustrip.(p.periods) |> join(_,":")
Regarding the use of Pipe, you can see endless discussions in recent thread here: https://discourse.julialang.org/t/fixing-the-piping-chaining-issue/89654 or just read the manual here (more useful): https://github.com/oxinabox/Pipe.jl
Another way using the above
DateTime variables is
julia> p = ts2 - ts1
julia> d = Dates.format(Dates.epochms2datetime(p.value),"H:M:S")
but note that you may need to check you’re not dropping the days off,cf. Conversion Functions.
p.value feels like intruding into
p internals, then
p/Millisecond(1) also works (perhaps slower).
All the answers were useful for me, thank you all. I wanted to make sure I didn’t have anything like the python3 result, ie: days, H:M:S
