format() returns wrong result when timezone is applied

[fabriziofortino]

Please take a look at the following code:

moment(1369627200000).format('wo [week] YYYY')
"22nd week 2013"

It looks correct. Applying a different timezone I get a wrong result:

moment(1369627200000).tz('America/New_York').format('wo [week] YYYY')
"27th week 2013"

This appears to be a valid bug, but it is only happening with the localized week of year formatters (w, wo, ww).

It appears to be working properly with the ISO week of year formatters (W, Wo, WW).

@mj1856 in some case even using ISO week year formatter the result is wrong.

moment(1375070400000).format('Wo [week] YYYY')
"31st week 2013" // correct

moment(1375070400000).tz('America/New_York').format('Wo [week] YYYY')
"35th week 2013" // wrong

Any idea?

These should be working as expected in 0.1.0.

moment(1369627200000).format('wo [week] YYYY')
// 22nd week 2013
moment(1369627200000).tz('America/New_York').format('wo [week] YYYY')
// 22nd week 2013

moment(1375070400000).format('Wo [week] YYYY')
// 30th week 2013
moment(1375070400000).tz('America/New_York').format('Wo [week] YYYY')
// 31st week 2013
