For Bolivia, the zone is written as follows in southamerica file:

For this case (third line), I am not entirely sure what the significance of Rule "1:00" is. Can anyone shed some light?
It is claiming that from 15 Oct 1931 to 21 Mar 1932, La Paz, Bolivia, was observing a clock offset of one hour relative to their normal local meridian time. For those five months their clocks were set 3:32:36 behind GMT. Then, on 21 Mar 1932 Bolivia changed to use a standard time offset of 4 hours behind GMT (or UTC, as the case may be), and has not changed since. --Ken Pizzini
