 * NOTE: KEEP THIS AT THE TOP OF E107.JS!
 * localTime is recorded ASAP after page load; SyncWithServerTime is called at the END
 * of page processing. We want localTime and serverTime set in close chronological order.
 * Page Processing order is as follows:
 * A) All PHP code encountered sequentially in page
 * B) All Javascript code encountered sequentially in page NOT including function internals
 * So best proximity is achieved by setting
 * serverTime at END of php code, and localTime at START of js code.
 * NOTE: this method means reported times include transfer delay. It's slightly MORE accurate this way!
 * Final product: tdOffset cookie contains server-browser time difference in seconds,
 * independent of time zone. tzOffset contains browser time zone in minutes.

/* NOTE: if serverDelta is needed for js functions, you must pull it from
 * the cookie (as calculated during a previous page load!)
 * The value calculated in SyncWithServerTime is not known until after the
 * entire page has been processed.
