Timezone database error (Europe/Budapest)

[fzoli]

Description of the Issue and Steps to Reproduce:

I think I have just found a timezone database parse(?) error.

moment.tz("1890-01-01 00:00", "Europe/Paris").format()
// "1890-01-01T00:00:00+00:09" // OK

moment.tz("1890-01-01 00:00", "Europe/Bucharest").format()
// "1890-01-01T00:00:00+01:44" // OK

moment.tz("1890-01-01 00:00", "Europe/Budapest").format()
// "1890-01-01T00:00:00+01:00" // WRONG
// It should be "1890-01-01T00:00:00+01:16:20" (or at least +01:16)

moment.tz('1890-01-01 01:16:20', 'Europe/Budapest').clone().tz('UTC').format()
// "1890-01-01T00:16:20Z" // WRONG
// It should be "1890-01-01T00:00:00Z"

From the tzdb-2016j:

Zone	NAME		GMTOFF	RULES	FORMAT	[UNTIL]
Zone	Europe/Budapest	1:16:20 -	LMT	1890 Oct

It means, the tzdb is correct.
I guess the JS code is correct and the tzdb parser should be fixed (cause other time-zones are well-parsed).

Environment:
Chrome 55 on Ubuntu 14.04.5 LTS
System timezone: Europe/Budapest

console.log( (new Date()).toString()) // Sun Feb 26 2017 11:19:46 GMT+0100 (CET)
console.log((new Date()).toLocaleString()) // 2017. 02. 26. 11:19:46
console.log( (new Date()).getTimezoneOffset()) // -60
console.log( navigator.userAgent) // Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36
console.log(moment.version) // 2.17.1

I believe this is a dup of #308

I don't agree.

Explain this.

Moment

moment('1890-01-01T00:00:00Z').clone().tz('Europe/Paris').format()
// "1890-01-01T00:09:21+00:09" // CORRECT

moment('1890-01-01T00:00:00Z').clone().tz('Europe/Budapest').format()
// "1890-01-01T01:00:00+01:00" // WRONG
// It should be "1890-01-01T01:16:20+01:16"

Java DateTime API

@Test
public void testParisTime() {
    ZonedDateTime parisTime = OffsetDateTime.parse("1890-01-01T00:00:00Z").atZoneSameInstant(ZoneId.of("Europe/Paris"));
    Assert.assertEquals("1890-01-01T00:09:21+00:09:21", DateTimeFormatter.ISO_OFFSET_DATE_TIME.format(parisTime));
}

@Test
public void testBudapestTime() {
    ZonedDateTime budapestTime = OffsetDateTime.parse("1890-01-01T00:00:00Z").atZoneSameInstant(ZoneId.of("Europe/Budapest"));
    Assert.assertEquals("1890-01-01T01:16:20+01:16:20", DateTimeFormatter.ISO_OFFSET_DATE_TIME.format(budapestTime));
}

Cause I can not reopen this issue, I created a new one:
