发明名称 Detecting time zones using historical date sampling
摘要 Detecting time zones using historical date sampling is disclosed. In various embodiments, an offset between a system time and a reference time is determined for each of a plurality of sample points, to produce a resulting set of offsets. A representation of the set of offsets is computed. The representation of the set of offsets is used as a key to look up a time zone associated with the system.

主权项 1. A method of determining a time zone, comprising: receiving, at a client computer system, a table comprising mappings of key values to time zone identifiers, the table being received from a server, wherein the key values mapped to the time zone identifiers in the table comprise, as keys, hash values computed using a set of time offsets for each of the time zones associated with the server; determining, by the client computer system, a set of time offsets according to an offset between a system time and a reference time for each of a plurality of sample points, wherein the plurality of sample points comprise different date/time values; concatenating a plurality of time offsets included in the set of time offsets; computing a hash value of the concatenated plurality of time offsets; using the hash value as a key to look up, in the table, a time zone identifier associated with the client computer system; and communicating, by the client computer system, the time zone identifier associated with the client computer system to the server.
