Subject: [PATCH] libservicelog: Fix timezone handling in servicelog event
 parsing

Replace mktime() with timegm() when parsing datetime fields from SQLite
database. SQLite's DATETIME('NOW') returns UTC timestamps, but mktime()
treats input as local time, causing incorrect timezone conversions.

Use timegm() to correctly interpret the UTC timestamps from the database,
ensuring accurate time representation.
