This is a proposal letter from the revenue department of the Government of Madras regarding the adoption of standard time in India. The proposal discusses fixing an Indian Standard Time for all Indian railways and telegraphs. It will be precisely 5.30 hours ahead of Greenwich Mean Time and 9 minutes ahead of Madras Time. Additionally, the proposal suggests fixing a Burma Standard Time for use on all railways and telegraphs in Burma, which will be precisely 6.30 hours ahead of Greenwich Mean Time and 5 minutes ahead of Rangoon time.

The album contains archival documents related to the building, instruments and observations at the Madras Observatory. It mainly includes an old photo of the Madras Observatory, a photocopy of the first observation taken in 1786 from the observatory, two pictures of Kater's pendulum hung in front of the Haswell clock in the observatory, a sketch of the Madras Observatory building from 1848 Taylor's catalogue and painting of Madras coast by Daniel.

This fond was about pendulum clock used at the Madras Observatory manufactured sometimes in 1786. The clock is now in Kodaikanal Solar Observatory and still in working condition.

The item was about clock errors and rates of Madras taken in the year 1885.

The fond contains observations of the meridian circle reductions ( refers to the process of correcting the observed zenith distances measured by a meridian circle instrument ) taken from the Madras Observatory from the year 1862 to 1887. Meridian circle reductions refers to a process in astronomy and celestial navigation that involves observations made with a meridian circle instrument.
