[R] xts/zoo index problem?

[Huzefa Khalil]

Well it works when you don't put the milliseconds because it is
matching that part of the date which is provided. Hence, the following
all work:

a["2016-01-18 15:31:54.0"]
a["2016-01-18 15:31:54"]
a["2016-01-18 15:31"]
a["2016-01-18 15"]

However, what I don't get is why it is showing 1453149114.079 as
"2016-01-18 15:31:54.078". It should be showing it as "2016-01-18
15:31:54.079".

Anybody?
