Cause (Maintainer-confirmed cause): Known WSL2 clock skew after resume from sleep; Microsoft megathread says a kernel patch backport is awaited. apt's Check-Date rejects Release files dated in the (guest's) future.
Fix status: workaround_only
Workaround (not a fix): sudo hwclock -s after resume; wsl --shutdown.
Misleading approaches:
- Setting Acquire::Check-Date=false for apt: disables a security check instead of fixing the clock
Unknowns:
- Whether current WSL kernel releases include the backport
Evidence (public sources, summarized; not reproduced by this contributor):
- https://github.com/microsoft/WSL/issues/10006 (github_issue, unknown, maintainer_confirmed_cause): WSL team megathread: clock can skew after resume from sleep (S0); awaiting kernel patch backport; workarounds hwclock -s, systemd-based sync, [boot] command ntpdate in wsl.conf.
- https://raw.githubusercontent.com/Debian/apt/main/apt-pkg/acquire-item.cc (official_docs, unknown, documented_behavior): apt emits 'Release file for %s is not valid yet (invalid for another %s).' when the Release Date is in the future.
- https://raw.githubusercontent.com/Debian/apt/main/doc/apt.conf.5.xml (official_docs, unknown, documented_behavior): Check-Date (default true) enables time-related checks including rejecting release files dated in the future; disabling means time can't be trusted.

Problem details
- Observed symptom
- After resume, apt refuses Release files as not yet valid, TLS/JWT/AWS SigV4 requests fail with time-related errors; 'date' inside WSL lags Windows time.
- Context
- Product: WSL 2 Component: VM clock synchronization after host resume Operation: apt update, HTTPS/signed cloud API calls, builds inside WSL2 after the laptop resumes from sleep Affected versions: unknown Environment: Windows host with WSL2, after S0/modern standby sleep or hibernate Trigger: Host sleeps while the WSL2 VM is running; on resume the guest clock is not corrected.

Proposed fix: [WSL2 after Windows sleep/resume] Clock skew breaks apt ('Release file for ... is not valid yet (invalid for another ...)'), TLS cert validation, signed API requests — VM clock not resyn
Recommended action: Resync the guest clock (sudo hwclock -s, or ntpdate/chrony/systemd-timesyncd via systemd or a [boot] command in /etc/wsl.conf), or restart the VM with wsl --shutdown; do not disable apt date checks.
Option: Resync the WSL clock [evidence: documented_workaround]
Applies when: After sleep/resume
Steps:
1. sudo hwclock -s (or sudo ntpdate <server>)
2. Optionally automate via systemd time sync or /etc/wsl.conf [boot] command
3. Or wsl --shutdown and reopen
Expected: date matches host; apt/TLS work
