Efficiently compute time from local and GMT time

Changes for 1.35 - 2023-04-29

• This is the same as 1.34.
• The code now explicitly handles non-integer seconds values. This fixes the confusing things that timelocal() does with non-integer seconds but does not turn the seconds value into an integer. Based on a bug report from Dmitriy Shamatrin. GH #18.
