 *
 * *NOTE*: this is not an injectable instance, just a globally available mock class of `Date`.
 *
 * Mock of the Date type which has its timezone specified via constructor arg.
 *
 * The main purpose is to create Date-like instances with timezone fixed to the specified timezone
 * offset, so that we can test code that depends on local timezone settings without dependency on
 * the time zone settings of the machine where the code is running.
 *
 * @param {number} offset Offset of the *desired* timezone in hours (fractions will be honored)
 * @param {(number|string)} timestamp Timestamp representing the desired time in *UTC*
 *
 * @example
 * !!!! WARNING !!!!!
 * This is not a complete Date object so only methods that were implemented can be called safely.
 * To make matters worse, TzDate instances inherit stuff from Date via a prototype.
 *
 * We do our best to intercept calls to "unimplemented" methods, but since the list of methods is
 * incomplete we might be missing some non-standard methods. This can result in errors like:
 * "Date.prototype.foo called on incompatible Object".
 *
 * ```js
