I'm not able to reproduce the test failure locally (using 0.7 build 2549, two days old) and on windows.

[hustf]

On Windows, you can create a date like this:

...whereas on OSX (downloaded binary):

This is hopefully straightened out soon, because it's currently difficult to make this package work and test on both 0.6 and 0.7, both OSX and Windows.  | | |_| | | | (_| |  |  Version 0.7.0-DEV.2590 (2017-11-23 15:32 UTC)

[hustf]

The Windows behaviour above has changed with JuliaLang/julia#24459. Todays behaviour is:

'using Base.Dates' in 0.7 would hopefully work in 0.6 without the need for Compat. Unfortunately it does not work as expected in 0.7 yet (Windows):

There has been a long standing issue with windows nightly binaries, so it is quite likely they're older versions than the mac and linux binaries.

[hustf]

aviks, thanks, but downloading 0.7 binaries didn't work at all two days ago. julia-latest-win64 is 0.6.1 or dresses quite like it. The output above is from a local compilation on windows / cygwin.

[aviks]

I'd suggest merging this, and fixing any issues as they come up. Mac and linux tests on travis seems to pass on 0.6 and nightly.

[kshyatt]

Can we merge this? It would help CoverageBase...
