      GError** error
    )

#### Description [src]

An `ECalRecurResolveTimezoneCb` callback, which can be used with e_cal_recur_generate_instances_sync(). The `cal_cache` is supposed to be an `ECalCache` instance.

Available since: 3.26

#### Parameters

`tzid`

  Type: `const gchar*`

  A timezone ID.

  The data is owned by the caller of the function.
  The value is a NUL terminated UTF-8 string.

`cal_cache`

  Type: `gpointer`

  An `ECalCache`.

`error`

  Type: `GError **`

  The return location for a recoverable error.
