Vikram Rao

Vikram's first real encounter with date-time pain came in his second year as a developer, when a cron job that was supposed to run at 2:00 AM on the second Sunday of March simply... didn't. The system clock jumped from 1:59 AM to 3:00 AM for daylight saving time, and the scheduler never saw 2:00 AM exist. The job processed financial reconciliation data. It took two days to notice, and a week to untangle the downstream effects. He's been slightly obsessed with date-time correctness ever since.

Over fourteen years, he has built scheduling infrastructure for distributed teams, worked on timestamp pipelines that ingest billions of events per day, and debugged more timezone-related production incidents than he can count. His speciality is the kind of problem that only surfaces at scale or at boundary conditions: what happens when a user in Samoa creates a meeting on December 29, 2011 (the day Samoa skipped entirely when it moved across the International Date Line)? What does "daily" mean for a cron job when DST creates a 23-hour day in spring and a 25-hour day in autumn? How do you sort timestamps from different sources when one uses milliseconds and another uses seconds since epoch?

He holds a B.Tech in Computer Science and has spoken at multiple developer conferences on topics including "Timestamps Are Harder Than You Think" and "The Date-Time Talk Your Team Needs." His conference talks tend to be heavy on war stories and live demos of things breaking — an approach he finds more persuasive than slides full of best practices. He's also an active open-source contributor, most notably to the date-fns JavaScript library, where he's helped maintain timezone-related utility functions.

Vikram's writing style is unapologetically practical. He starts with the bug or the production incident, then works backward to the principle. His articles include working code in JavaScript, Python, and SQL — not toy examples, but patterns he's actually used in production systems. He's a firm believer that the right time to learn about date-time edge cases is before they page you at 3 AM, not after.
