[Boost-users] [date_time] timezone rules for different years

For my application, I need to be able to get the local time of any UTC time
in the last five years in any location.

As far as I can see, the date_time library doesn't provide this. The
documentation says that date_time_zonespec.csv is "based on data found in
the zoneinfo datebase", but whereas the zoneinfo database contains
historical information about daylight saving time changes,
date_time_zonespec.csv only seems to allow you to specify a single rule for
each timezone. And I can't find another mechanism to do it.

Am I missing something, or is this capability not present? And if not, is
there any plan to add it? Or a workaround? I anticipate that this will
become more of a problem when the rules for the U.S. change by several weeks
next year.

Thanks in advance for any tips, and Happy Christmas,
