[julia-users] Get time between two DateTime values in hours (and minutes if simple)

[Ian Butterworth]

Trying to get the number of hours between these two dates (ideally "x hours 
and y minutes"), but can't figure out how to convert the duration variable 
into hours. The bottom line currently errors

timein = "2015/8/13 10:19:50"
timein2 = "2015/8/14 13:12:34"

time_series[1] = DateTime(timein,"yyyy/mm/dd HH:MM:SS")
time_series[2] = DateTime(timein2,"yyyy/mm/dd HH:MM:SS")

duration = time_series[2]-time_series[1]
Dates.Hour(duration)
