Hi Leon,

Yes, but the problem is that the offset for Berlin in Boost date_time_zonespec.csv is +01, not -01

Just to avoid ambiguity - it's probably not the date_time_zonespec.csv entry that is broken (local system may use any notation they wish), and from what I saw Boost.DateTime does not claim that this file has contains Posix strings. Quite the opposite, the documentation on the offset field is very explicit:

- GTM offset: This is the number of hours added to utc to get the local time before any daylight savings adjustments are made. Some examples are: America/New_York offset -5 hours, and Africa/Cairo offset +2 hours. The format must follow the length-of-time format described above.

On the other hand, the documentation for to_posix_string() method does claim that it, in accordance with its name, returns a Posix compliant string.

Cheers,

Leon
