Time

So what time can be trusted? My mobile's? My PDA's? Clocks which I see in the streets also can't be trusted, they usually show differing times. Maybe they got broken because all the clock adjustments because of the light savings. One of my mobile's even offers an automatic time adjustment, which would confuse me even more: did it accept the different time zone? The light saving? I can never be sure. I tend to set all my hands to GMT or UTC ( oh my god, even the standards vary, haha). This would also giving my brain giving a good exercise, especially in the morning when the alarm clock shrills: "Oops: summer time? Winter time? GMT? UTC? Fuck it, back to the pillows!!
