The official history from some well-research Unix timezone work has
Nepal being 5:41:16 ahead of GMT until 1920, then 5:30 until 1986,
and now 5:45 ahead, which is closer to their older value.
Timezones didn't come into being until the 1880s.

Paul:
There are some weird ones. India is on the half-hour (GMT +5:30). Nepal
used to be...maybe still is... 40 minutes off the hour (just to be different
from India) at GMT +5:40 :-))
There may be others.
