if for any reason you communicate with people in other time zones, i recommend using this nice little multiple clock program for windows, zone tick. i have used them for several years & am v happy with the product (i have nyc, london & melb as my clocks).
recently they sent out a promo where paid folks can offer their friends a fully functional version that runs til october 1st. if you’re interested in trying it, download it (though i think they said the promo only runs til the 9th of aug or something.
