Abstract
Time stamps for time series data can be efficiently compressed by grouping rows in a database table such that time stamp values of the rows in the group are ordered and characterizable by an increment and an offset, which can be stored for the set of rows respectively in an increment column and an offset column such that the time stamp values of the set of rows are represented by a single slope and offset. A run-length compression can be applied to the increment column and offset column for the table.
