maya.when() accepts string containing epoch, but computes wrong time

[LuccoJ]

In [14]: epoch=str(maya.now().epoch)

In [15]: str(maya.MayaDT(epoch))
Out[15]: 'Fri, 17 Nov 2017 23:59:38 GMT'

In [16]: str(maya.when(epoch))
Out[16]: 'Sat, 18 Nov 2017 00:59:38 GMT'

I guess it should either return the same value as the constructor does, instead of apparently the value shifted by an hour (which might be timezone-dependent), or simply refuse to process this type of input (which is what maya.parse() does):

In [17]: str(maya.parse(epoch))
[...]
ParserError: Invalid date string: 1510963178

when is for human dates, parse is for machine dates.

[kennethreitz]

we have a seperate method for from_epoch

I still think that in that case it should refuse to process the non-human date, instead of silently processing it wrong by a subtle amount of time... also considering that almost by definition, when you're processing dates input by a human, you cannot know what exactly to expect, so if the human somehow decides to input an epoch instead of a standard human date, that should probably result in an exception, not a silent failure.
