## Quick Start
81+
82+
Get up and running in seconds:
83+
84+
```go
85+
package main
86+
87+
import (
88+
"fmt"
89+
"github.com/agentstation/utc"
90+
)
91+
92+
func main() {
93+
// Get current time in UTC
94+
now := utc.Now()
95+
fmt.Println("Current UTC time:", now.RFC3339())
96+
97+
// Parse and convert to different formats
98+
t, _ := utc.ParseRFC3339("2024-01-15T10:30:00Z")
99+
fmt.Println("US format:", t.USDateShort()) // "01/15/2024"
100+
fmt.Println("EU format:", t.EUDateShort()) // "15/01/2024"
101+
fmt.Println("Pacific time:", t.Pacific()) // Auto PST/PDT
102+
}
103+
```
104+
105+
## UTC vs Standard Library ⚡
106+
107+
See the difference between `utc` and Go's standard `time` package:
108+
109+
| Feature | Standard `time.Time` | `utc.Time` |
110+
|---------|---------------------|------------|
111+
| **Timezone Safety** | ❌ Manual timezone handling | ✅ **Always UTC, automatic conversion** |
112+
| **Nil Safety** | ❌ Panics on nil receiver | ✅ **Returns errors gracefully** |
113+
| **Dependencies** | ✅ Zero deps | ✅ **Zero deps** |
114+
| **Rich Formatting** | ❌ Manual layout strings | ✅ **Built-in US/EU/ISO formats** |
115+
| **Timezone Conversion** | ❌ Manual location loading | ✅ **Auto PST/PDT, EST/EDT handling** |
116+
| **JSON Ready** | ✅ Basic support | ✅ **Enhanced parsing & formatting** |
117+
| **Database Ready** | ✅ Basic support | ✅ **Enhanced Scan/Value methods** |
118+
| **Production Safety** | ❌ Can panic unexpectedly | ✅ **Error-first design** |
119+
120+
**Before** (standard library):
121+
```go
122+
loc, _ := time.LoadLocation("America/New_York")
123+
t := time.Now().In(loc) // Hope timezone exists!
124+
if t != nil { // Manual nil checking
125+
fmt.Println(t.Format("01/02/2006")) // Remember layout
126+
}
127+
```
128+
129+
**After** (with UTC):
130+
```go
131+
t := utc.Now()
132+
fmt.Println(t.Eastern().Format(time.Kitchen)) // Auto EST/EDT
133+
fmt.Println(t.USDateShort()) // "01/15/2024"
134+
// No panics, no manual timezone loading, no layout memorization!
135+
```
