 minutes 40 seconds (96° 10') in advance of Greenwich Mean Time, 

 whereas Burma Standard Time is (i hours 30 minutes ( ( .)7 30') in 

 advance of Greenwich Mean Time. 



The oflicial guide book of the Burma Railways states that

of scismological calculations, the great majority 

 of them from scattered places in the province are worthless, as 

 the differences even in times which are said to have been compared 

 with Standard Railway or Telegraph Time in the same towns, 

 are often very apparent and mutually irreconcilable.
