/*

 * 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.

 * The value calculated in SyncWithServerTime is not known until after the

 * entire page has been processed.
