If we take the below example: committer Name <user@domain> 1557948240 -0400 and we follow the rule that: 1. any trailing zero after the decimal point MUST be omitted 2. if there are no digits after the decimal point, it MUST be omitted This would allow: committer Name <user@domain> 1557948240 -0400 committer Name <user@domain> 1557948240.12 -0400 but the following are never allowed: committer Name <user@domain> 1557948240. -0400 committer Name <user@domain> 1557948240.000000 -0400 By following these rules, all previous commits' hash are unchanged. Future commits made on the top of the second will look like old commit formats. Commits coming from "older" tools will produce valid and mergeable objects. The loss precision has frustrated us several times as well. Respectfully, Jason Pyeron
