use lal routines for GPS time handling
As @kipp.cannon suggests, although the specific issue in #9 (closed) is fixed, using LAL for gps time handling is probably a more robust solution long-term to avoid future problems.
Maintenance will be performed on git.ligo.org, containers.ligo.org, and docs.ligo.org on Tuesday 30 April 2024 starting at approximately 9am PDT. It is expected to take around twenty minutes and there will be several periods of downtime throughout the maintenance. Please address any comments, concerns, or questions to the helpdesk.
