parse_date and parse_datetime not converting abbreviated month names

[ryangarner]

I'm having an issue with parse_date and parse_datetime recognizing %b (abbreviated name in current locale). Do I need to change LC_TIME?

as.Date("1jan1960", "%d%b%Y")
[1] "1960-01-01"
parse_date("1jan1960", "%d%b%Y")
[1] NA
Warning message:

strptime("1jan1960", "%d%b%Y")
[1] "1960-01-01 UTC"
parse_datetime("1jan1960", "%d%b%Y")
[1] NA

That's currently a known problem :/

The problem here is actually capitalisation. This works:

parse_date("1 Jan 1960", "%d %b %Y")
