Do we need adjustment in Vikram Samvat?

"Nepali Times", a news paper from Nepal, has come up with the news that the Nepali Bikram Era need to be adjusted as it is going a month behind the sun. The rationale mentioned is as follows -

"Calendars are based on the earth’s motions: around its own axis, and around the sun in its orbit. But the axis has a slight wobble. In relation to the stars, the earth takes 365 days, six hours, nine minutes and 10 seconds to complete one revolution. This is the sidereal year. With respect to its orbit, the earth takes 365 days, five hours, 48 minutes and 46 seconds to complete one tropical year. This difference of 20 minutes and 24 seconds every year is caused by the earth’s wobble."

The complete story can be found here -

Adjusting Nepali time

The question raised here is nothing but a good old ayanamsa question. As the sidereal zodiac shifts around 50.33 arcs per year, equilant adjustment is request in the sidereal calendar which is around one day in every 70 years.

I am not much sure about it. The strange point is that I have seen this story in a Nepali newspaper not in an Indian newspaper. If the Nepali calendar (Bikram Era) needs and adjustment, the Hindu calendar (Vikram Samvat) will need that adjustment too. But why no one is not talking about it?
