--------------- original answer above is way too big, improved below -----------

There are 36 possible answers,

depends on how many leap years in those 35 years,

starting the normal 35 years (no leap years):

60 * 60 * 24 = 86400 seconds/day

86400 * 365 * 35 = 1103760000 seconds / normal year

for 1 leap years in those 35 : 1103760000 + 86400 = 1103846400

for 2 : 1103760000 + 86400 * 2

for 3 : 1103760000 + 86400 * 3

...

for 35 leap days: 1103760000 + 86400 * 35 = 1106764000

so, the answer is between [1103760000,1106764000]
