摘要： A method and system for maintaining date and time information correctly across rule changes for time zones is provided. A time maintenance system provides rules for converting dates and times between various time zones and a common time zone. When the time maintenance system receives a date and time in a designated time zone, it converts the date and time to a date and time in the common time zone based on a provided rule. The time maintenance system then stores the converted date and time along with an identification of the rule used to convert the date and time to the common time zone. The time maintenance system may then receive an indication of an overriding rule that overrides an existing rule for converting a date and time between the designated time zone and the current time zone. The time maintenance system then updates the stored date and time when the rule has been overridden in such a way as to indicate that the original date and time is no longer correct and to indicate the new rule.

摘要： A compressed trie has nodes including multiple character sub-strings. Such multiple character storage reduces the number of nodes in the trie, thereby reducing the amount of memory required for storing the trie and reducing the amount of time required to perform matching. Furthermore, in such a compressed trie, sub-strings are stored in a single character string. Each node references its corresponding sub-string by the sub-string's starting position and length in the character string. Multiple nodes may reference a single sub-string. Thus, referencing rather than storing sub-strings in corresponding nodes eliminates repetitive sub-string storage, thereby reducing the amount of memory required for storing the trie.
摘要翻译：压缩特技包含多个字符子串的节点。这种多字符存储减少了特里部分中的节点数量，从而减少了存储所需的内存所需的内存量，并减少了执行匹配所需的时间量。此外，在这样的压缩特技中，子串被存储在单个字符串中。每个节点通过子字符串的起始位置和字符串中的长度引用其对应的子字符串。多个节点可以引用单个子串。因此，引用而不是将子串存储在相应的节点中消除了重复的子串存储，从而减少了存储该线索所需的内存量。
