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.
