From 691d6b33ee7454f9559239b86387bb5673274bec Mon Sep 17 00:00:00 2001 From: Lars Henriksen Date: Sun, 19 Nov 2017 22:51:57 +0100 Subject: Check for the year span 1902-2037 Reintroduce year check for systems with a 32-bit time_t type. Remove the lower limit (1902) for systems with a 64-bit time_t. This limits movements in the calendar (for 32-bit systems) and in no way ensures constistency of data. Commit a12833e (Handle dates past January 19th, 2038, 2015-01-19) removed the upper limit (2037) on dates but left the lower limit (1902). It did not ensure the support of the target system.
