Methods summary
`public static array`	# `getOffsetsFromSyncTZ( base64 $data )` Convert a timezone from the ActiveSync base64 structure to a TZ offset hash. Convert a timezone from the ActiveSync base64 structure to a TZ offset hash. Parameters `$data` timezone structure defined by MS as: <pre>typedef struct TIME_ZONE_INFORMATION { LONG Bias; WCHAR StandardName[<span class="php-num">32</span>]; SYSTEMTIME StandardDate; LONG StandardBias; WCHAR DaylightName[<span class="php-num">32</span>]; SYSTEMTIME DaylightDate; LONG DaylightBias;};</pre> With the SYSTEMTIME format being: <pre>typedef struct _SYSTEMTIME { WORD wYear; WORD wMonth; WORD wDayOfWeek; WORD wDay; WORD wHour; WORD wMinute; WORD wSecond; WORD wMilliseconds; } SYSTEMTIME, *PSYSTEMTIME;</pre> <p>See: http://msdn.microsoft.com/en-us/library/ms724950%28VS.85%29.aspx and: http://msdn.microsoft.com/en-us/library/ms725481%28VS.85%29.aspx</p> Returns `array` Hash of offset information
`public static string`	# `getSyncTZFromOffsets( array $offsets )` Build an ActiveSync TZ blob given a TZ Offset hash. Build an ActiveSync TZ blob given a TZ Offset hash. Parameters `$offsets` A TZ offset hash Returns `string` A base64_encoded ActiveSync Timezone structure suitable for transmitting via wbxml.
`public static`	# `getOffsetsFromDate( Horde_Date $date )` Create a offset hash suitable for use in ActiveSync transactions Create a offset hash suitable for use in ActiveSync transactions Parameters `$date` <p>A date object representing the date to base the the tz data on.</p>
`public array`	# `getTimezone( array\|string $offsets, string $expectedTimezone = null )` Attempt to guess the timezone identifier from the $offsets array. Attempt to guess the timezone identifier from the $offsets array. Parameters `$offsets` <p>The timezone to check. Either an array of offsets or an activesynz tz blob.</p> `$expectedTimezone` <p>The expected timezone. If not empty, and present in the results, will return.</p> Returns `array`
`public array`	# `getListOfTimezones( array\|string $offsets, string $expectedTimezone = null )` Get the list of timezone identifiers that match the given offsets, having a preference for $expectedTimezone if it's present in the results. Get the list of timezone identifiers that match the given offsets, having a preference for $expectedTimezone if it's present in the results. Parameters `$offsets` <p>Either an offset array, or a AS timezone structure.</p> `$expectedTimezone` The expected timezone. Returns `array` An array of timezone identifiers
