From: Chris Bagwell Date: Tue, 12 Apr 2022 19:51:48 +0000 (-0500) Subject: Convert 64-bit time value to time_t as needed X-Git-Tag: v12.6.0~2^2 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a7628664136cd273b3d91fb9b6d8881d87bd8069;p=sysstat Convert 64-bit time value to time_t as needed On platforms with 32-bit time_t, code up converts it to a 64-bit data type. The pointer to this 64-bit value is incorrectly passed to a few functions that accept a pointer to a 32-bit time_t. On little endian platforms the original 32-bit time_t value will be visible this way but on big endian platforms only zeros will be seen and time will be show as wrong values. Update code to convert to time_t to be compatible with 32-bit be platforms. --- diff --git a/sa_common.c b/sa_common.c index 035c07d1..c2c8ce1 100644 --- a/sa_common.c +++ b/sa_common.c @@ -755,6 +755,8 @@ void get_itv_value(struct record_header *record_hdr_curr, void get_file_timestamp_struct(uint64_t flags, struct tm *rectime, struct file_header *file_hdr) { + time_t t = file_hdr->sa_ust_time; + if (PRINT_TRUE_TIME(flags)) { /* Get local time.
