Why Timezone Scheduling Actually Matters for Automated Screenshots
A capture scheduled for “9 AM” should run at 9 AM in the timezone you chose — not UTC, not server time, not “close enough”. This guide explains why timezone-aware scheduling prevents missed launches, broken proofs, and confusing archives.
If you automate website screenshots, timing is the whole game. You’re not capturing “a page”—you’re capturing a moment: a promo going live, a banner flipping, a price changing, a cookie notice appearing, a compliance footer updating, or a competitor launching.
The screenshot should match what a real user saw at that local time.
Daylight saving shifts shouldn’t break schedules silently.
Your archive must line up with events, launches, and evidence.
What timezone scheduling really means
It’s not about UTC conversion. It’s about preserving human intent.
Humans schedule by local time. Businesses announce launches by local time. Promotions start and end by local time. Even when your team is global, the “truth” of a page change is almost always tied to a region: US time, EU time, APAC time, or a specific customer’s timezone.
Proper timezone scheduling stores three things together: time, recurrence, and timezone. If any one is missing, you get drift.
America/New_York or Europe/Berlin (IANA timezones). Avoid “UTC+X” offsets for recurring jobs.Where UTC-only scheduling breaks
UTC is fine internally — but it’s not a user-facing scheduling language.
Many systems store schedules in UTC and force users to convert “9 AM local” into “some UTC hour”. That’s already error-prone… and then daylight saving enters the chat.
- DST shifts: “9 AM local” becomes “8 AM local” (or “10 AM local”) after DST unless the timezone is stored properly.
- Team confusion: different teammates interpret “daily at 9” differently if the timezone isn’t explicit.
- Cross-region monitoring: a “global” schedule is meaningless when the website behavior is regional.
- Evidence mismatch: your archive timestamps don’t match the real-world moment you needed to capture.
Real-world examples of missed captures
These are common failure cases we see across teams.
1) Promotions that start “at 9 AM”
A banner flips at 9 AM local time (for a region). A UTC-only schedule captures too early or too late and misses the “first moment” version.
2) Regional cookie / consent banners
Some banners are time-windowed. If your captures run outside EU business hours, you never see the banner and falsely conclude it’s missing.
3) Price changes aligned to local midnight
A competitor updates pricing at midnight in Tokyo. A “daily” UTC capture misses the actual switchover and captures the wrong version for hours.
How we handle timezones + DST
Schedules are stored with their timezone and remain correct over time.
We support timezone-aware scheduling where the timezone is stored along with the job configuration. This means a schedule like “daily at 9 AM in America/New_York” continues to run at 9 AM New York time — even when daylight saving changes.
We store a named timezone with your schedule, not just an offset.
Daylight saving transitions don’t shift your local schedule unexpectedly.
Captures align with the real-world moment your team expected.
Scheduling frequency options
From high-frequency monitoring to monthly evidence snapshots.
Different monitoring goals require different intervals. A pricing page might need hourly checks. A compliance footer might be daily. A long-term archive might be weekly or monthly.
| Option | Best for | Notes |
|---|---|---|
| Every 10 minutes | Fast-moving pages, incident monitoring | Great for short windows, not always needed forever |
| Hourly | Pricing, stock status, key landing pages | Good “balanced” monitoring without overload |
| Daily | Brand monitoring, SEO pages, compliance checks | Most common interval for long-term monitoring |
| Weekly | Competitive snapshots, stakeholder reports | Ideal for “review packs” and summaries |
| Monthly | Archival evidence, audits, historical records | Perfect for long retention with low noise |
Custom schedules (minimum every 10 minutes)
When your monitoring needs don’t fit a simple preset.
Presets are perfect for most teams, but sometimes you need a custom rhythm. For example: capture every 10 minutes during a launch window, then drop back to daily afterwards. Or capture frequently during business hours and less frequently overnight.
We support customizable schedules with a minimum interval of every 10 minutes. That means you can build workflows that match reality without hacks or duplicated jobs.
- Launch day: every 10 minutes for 3 hours
- Business hours: hourly, weekends: daily
- Promo windows: extra captures right before start/end
Daylight saving time (and why it breaks so many tools)
If your tool stores offsets, DST will eventually bite you.
Daylight saving time isn’t just a “one-hour shift.” It’s a recurring source of silent scheduling drift when tools store schedules as offsets (UTC+X) instead of real timezones.
A correct implementation stores the timezone identifier (e.g. America/New_York) and uses it to compute the next run time. That’s how “9 AM local” stays “9 AM local” year-round.
How to change your timezone
Update your timezone any time — without doing UTC math.
You can change your timezone from your account area. This is useful when your team relocates, when the “source of truth” timezone changes, or when you’re configuring schedules for a specific customer or region.

Small scheduling choices prevent big archive problems.
- Use named timezones (e.g.
Europe/Paris) instead of offsets (UTC+X). - For launches, capture 10–15 minutes before the expected change time (pages often deploy gradually).
- Don’t overschedule forever — use higher frequency only during high-risk windows.
- If a page is region-specific, create separate schedules per region instead of one “global” schedule.
Workflows by team type
How different teams use timezone scheduling in practice.
Global marketing
Schedule regional landing pages in the region’s timezone. Increase capture frequency during launch windows, then return to daily.
Compliance teams
Capture region-specific banners during the time windows they appear. Keep a timezone-aligned archive so evidence matches local regulations.
Affiliate / promo monitoring
Set schedules around promo start/end in the promo timezone. Capture slightly early and slightly late to avoid edge-case timing differences.
FAQ
Quick answers.
UTC is fine internally, but users should never be forced to think in UTC. The problem is when “9 AM local” becomes “some UTC hour” and then drifts with DST or region changes.
The minimum interval is every 10 minutes. You can also choose predefined schedules: 10 minutes, hourly, daily, weekly, and monthly.
Yes. Schedules are timezone-aware and remain aligned to the selected timezone when DST changes.
You can change it from Account Manage or directly at Account TimeZone.
TL;DR
The shortest explanation that still stays true.
If you’re automating screenshots, the timezone is part of the schedule. Without it, captures drift, promotions get missed, and archives become unreliable evidence.
Start timezone-aware scheduling
Choose 10 minutes, hourly, daily, weekly, monthly, or a custom schedule (minimum every 10 minutes). Your timezone stays correct — even with DST.
