- Does not include leap seconds (27 of them so far, so subtract 27 seconds
- Birth time was daylight savings time, fall back subtracts an hour
- hence: 23148 days 2 hours, 32 minutes, 53 seconds
- My birth certificate says 1953, 5 September, 0745 (PDT)
- So my 2 gsec time of day is 1017 and 53 seconds
- presumably plus or minus 10 minutes, they were watching a birth, not the clock or the paperwork
