I am using R on the Azure machine learning, and I have some problems.

I want to use program R to calculate the difference between two dates, for example, 2014/11/01 and 2014/11/03.

I use the function "strptime" in R to do this thing, it can work on my own computer, but when I want to run the same code on Azure ml, it came out the error.

The error is :

[ModuleOutput] 1: In strptime(x, format, tz = tz) :


[ModuleOutput]   unable to identify current timezone 'C':


[ModuleOutput] please set environment variable 'TZ'


[ModuleOutput] 2: In strptime(x, format, tz = tz) : unknown timezone 'localtime'

I think the problem is that it can't detect the timezone on Azure ml, but I'm not sure.

Is there any way to solve this problem?

The problem is that Azure will detect the CSV automatically. And it regards the date string as the date form. So you can't use the original R code to show the same output.
