This class represents abstract time zone and provides
30
basic interface for type::Time <-> type::Time::epoch_t conversion.
31
Actual time zones which are specified by DB, or via offset
32
or use system functions are its descendants.
34
class Time_zone: public memory::SqlAlloc
38
Converts time in type::Time::epoch_t representation to local time in
39
broken down type::Time representation.

virtual void gmt_sec_to_TIME(type::Time &tmp, type::Time::epoch_t t) const = 0;

We need this only for surpressing warnings, objects of this type are
45
allocated on memory::Root and should not require destruction.
